Improved Gluten Free Sandwich Bread Recipe.

From what I have been seeing over the past year, just like cars and technology, gluten free bread is being upgraded with new and improved recipes. Curious as I am to this and always fine tuning my own recipe, I embarked on a trial and error series of several recipes that I had drafted together. I gathered my research from recipes I had been studying that used ingredients I hadn't tried in gluten free bread baking. But after seeing such great and successful results I had to try these recipes out for myself.

The recipe I have settled with (for now) is adapted from Fork and Beans Gluten-Free Vegan Bread recipe. I followed the recipe near true to form with the change of flour blend and binders. I also adapted the method in making the bread. I was pleased with the results. The pictures say it all! Soft yet strong bendy bread with a golden crust, even crumb and great flavour!

So without further delay, here is my new and improved gluten free bread recipe.

Gluten Free Sandwich Bread

Wet Ingredients:
240 ml warm milk
240 ml warm water
3 tbsp vegetable oil
2 tsp white vinegar
2 tbsp pysllium husk
1 tbsp chia seed
1 tbsp flaxseed

Dry ingredients:
420 g gluten free flour blend (see below)
1 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
2 tsp sugar
1 sachet of instant dried yeast

Grind psyllium husk, chia seeds and flaxseeds to a course powder in a coffee grinder.
In a large bowl, whisk together the dry ingredients.
Whisk the milk, water, oil, vinegar, and ground binder mix until well-combined. Allow to sit for 2 minutes to coagulate.
Pour the wet ingredients into the dry and mix with a spoon until just combined. Spoon the dough into a 9x4x4 lined loaf pan. Dip your hand or spoon into water to smooth out the top and very gently press down to ensure the dough is distributed evenly and there are no gaps/holes.
Warm your microwave oven by heating a cup of water for 1 minute or until boiling. This provides a warm and moist environment for the dough to rise in.
Cover and seal the dough in a plastic bag and place in warmed microwave. Allow to rise until the dough has doubled in size, about an hour. Leave the microwave door slightly ajar so the light remains on, keeping a warm environment.
Preheat oven to 190°C (350°F).
When dough has risen place in the oven on the middle rack and bake for 60 minutes, until bread is golden brown and sounds hollow when tapped. Remove from the oven and allow to cool briefly in the pan until you can remove it then transfer to a wire rack and leave to cool completely.

Gluten Free Flour Blend 

(This makes enough for the bread recipe above)

70 g each of:
millet flour
sorghum flour
buckwheat flour
glutinous rice flour
tapioca flour
potato starch

Sift all of the ingredients into a large bowl.
Then using a large whisk, thoroughly mix together all the flours.

I make a large batch that way I have my own ready-to-use gluten free flour mix. Just triple the equal part measurements of each flour, e.g., 210 g each of millet flour, sorghum flour, buckwheat flour, glutinous rice flour, tapioca flour and potato starch.

New and Improved Flour Blend!

I have been experimenting with a few different blends of flours and balances of flour to starches and thought I would share my knowledge and discoveries with you all.

As a rule, I tend to avoid using rice flour for gluten free bread baking as I have found its quite stiff, heavy and doesn't rise well. But after seeing some recipes using glutinous rice flour and the wonderful light results it was providing I had to give it a try. It has the same characteristics of what starch flours provide in gluten free baking but its not a starch. Don't be put off by the 'glutinous' word, its still gluten free. Glutinous or sweet rice flour is milled from a special variety of rice, often known as "sticky rice," that is very starchy and has exceptional binding qualities. It is an excellent ingredient for gluten free baking. Glutinous rice is relatively healthy, having an extremely low fat content, but it doesn't offer the nutritive value of brown or wild rice. Still it does contain more vitamins and minerals than starch flours. So I have added it to my flour blend.

I usually use a 60% wholegrain flour 40% starch blend. But once again after seeing better results with a 50-50% blend I have switched to this ratio. I wanted to keep the nutritional value in my gluten free flour blend on the higher side which is why I stuck with the 60-40% ratio. A lot of store bought  gluten free premix blends and store bought gluten free baking products are mostly starches with no nutritional value at all. A 50-50% balance still provides beneficial nutrition factors and also better results in your baking.

The blend of flours and starches I have been recently using is equal parts of the following:
  • millet flour
  • sorghum flour
  • buckwheat flour
  • glutinous rice flour
  • tapioca flour
  • potato starch

To make your own gluten free flour blend, into a large bowl sift in equal measurements of the above flours. Then using a large whisk, thoroughly mix together all the flours. Store in an air tight container.

Now I just want to recap a few differences with some flours and starches that catch people out.

Tapioca Flour and Starch

Tapioca flour and tapioca starch are the same thing and can be used interchangeably in your recipes. Tapioca flour and starch are made from the cassava root. They provide lightness and elasticity to the texture of foods and can also be used to thicken sauces.

Potato Flour and Starch

Potato flour and potato starch are two completely different products. The starch is made from raw potato and is fine and light. The flour is made from cooked potato and is much heavier than starch. The two cannot be used interchangeably in recipes.

Corn Flour and Starch

Corn flour and corn starch are also very different. Corn flour is yellow and slightly sweet, while corn starch is white and bland tasting. Corn starch is a popular thickener for sauces. In some countries the names are used interchangeably so what is corn starch is labelled corn flour. Also watch out for corn flour/starch made from wheaten. This is not gluten free and made from wheat.

So don't be afraid to experiment with what ever flours and starches you can get your hands on. Just remember that measuring by weight is going to be more accurate than measuring by volume thus satisfying results.

My Gluten Free Bread Recipe!

I have adapted this recipe from my research of many other gluten free bread recipes out there and I still feel I could play around with this one but for now I make this with confidence I will get a great sandwich loaf.
If you have any questions revert to my pages in the blog, everything this recipe is made of comes the information I have gather and written in the blog.
So get your apron on and start baking and eating your own homemade gluten free bread!!!!!

In a bowl thoroughly whisk together:
100 grams Sorghum Flour
100 grams Millet Flour
100 grams Buckwheat Flour
75 grams Tapioca Starch
75 grams Potato Starch
10 grams Ground Flaxseed
1 1/4 tsp Salt
2 tbsp Sugar
2 1/4 tsp or 1 sachet Instant Dried Yeast

In the bowl of your stand mixer with paddle attachment, mix together
20 grams Psyllium Husk
400 grams Tepid Water
4 tsp Vinegar

When the wet mixture thickens to form a gel approx 2-3 minutes, add:
2 tbsp oil

Mix for another minute then add the bowl of dry ingredients and mix for several minutes until well-combined.

Place the dough out into a lightly-oiled bowl, cover the top with oiled plastic wrap touching the surface of the dough. Put the whole bowl in a plastic bag and let rise for 30 minutes - 1 hour in a warm place like on top of your hot water cylinder.

When the dough has risen, turn out onto a lightly-oiled surface and gently deflate by pressing out and roughly shaping the dough into a rectangle shape.

Starting at the short side, tightly roll the dough up, tucking the ends as needed, to form a cylinder. You are trying to create a dense, tight loaf with good surface tension, such that it will hold it’s shape during the final rise and baking.

Tuck the short ends into the loaf and pinch along all the seams to seal.

Finish shaping dough into a loaf by rolling it lightly back and forth (with your hands on top, like using a rolling pin) for a smooth, rounded finished look.

Place the formed dough seam side down in a loaf pan lined with baking paper and cover with oiled plastic wrap to prevent the dough from crusting over. Let it rise in a warm place for 1 hour - 1 1/2 hour, or until the dough no longer springs all the way back when dented with a finger.

Place a tin foil tent cover and open at the ends. Bake the bread in a 210°C oven for 25 minutes, then turn the oven down to 190°C and cook until done, another 20-30 minutes. Remove the tent foil in the last 10 minutes. The loaf is done when tapped on the bottom will sound hollow.

Let your bread cool completely before slicing. Store your bread in a dry cool place wrapped in a plastic bag for several days and it can be kept frozen for up to 6 months. Just pull a couple of slices out the day before if you wish to make sandwiches or toasted straight out of the freezer. Enjoy eating gluten-free bread!

Baking A Gluten Free Sourdough Loaf: Putting Theory To Practice.

The process of sourdough from start to finish is a long road but it is a road well worth travelling for the outcome is rewarding and satisfying. Cataloging every step has left me with many questions to the gluten free sourdough process so there is much more baking to be done yet I was not disappointed. Some techniques used in regular sourdough need to be trialed for gluten free sourdough but for now this is process I tried and share with you to put into practice.

Gluten Free Sourdough Starter:

You will need:
100g of gluten free flour (I used a blend of wholegrain flours and measured out equal amounts of sorghum, buckwheat and millet)
100g of filtered room temperature water
A large jar
A piece of cheese cloth
A elastic band
A whisk or fork

Whisk flour and water in a small bowl. Pour this into the jar. Cover with a cheesecloth securing it around with elastic band and let sit for 12 hours at room temperature.
After 12 hours, whisk the starter and add 50g flour and 50g water, mix together. Cover and let sit for 12 hours at room temperature. Continue adding 50g flour and 50g water every 12 hours for up to a week.

24 hours

48 hours

72 hours

96 hours
There's more detail about creating and maintaining your starter here.

The starter should be “spongy” in appearance with maybe some foamy bubbles on top and some air pockets in the mixture. It should have a slight sour smell. Your starter is now active and is ready to be used.

Gluten Free Sourdough Bread Recipe:

Mix in the bowl of a stand mixer until a gel forms:
350g spring water at room temp
20g psyllium husk
10g ground flaxseed

300g starter 100% hydration
300g gluten free flour blend (60g each of sorghum, millet, buckwheat, tapioca and potato starch)
24g sugar
1 tsp salt

Mix everything until well blended.  Scoop dough out and form into an oblong shape and set to rise on parchment paper in a loaf pan.  Cover the top with plastic touching the surface of the dough.  Put the whole pan in a plastic bag and let rise 4-12 hours.  The longer it rises the more sour it will be but the less oven spring you will get.

Shaped dough

Dough before rise

Dough after rise

Preheat oven to 200°C (390°F) with a heavy baking sheet or pizza stone inside.  Score the bread, brush with water, cover with a tin foil tent cover and open at the ends then carefully place it in the hot oven. Bake until when the loaf is tapped it sounds hollow, about 40 minutes. Remove the tent foil and bake until the crust feels crisp on top, about 10 minutes.  Let cool several hours before slicing.

As you can see this recipe creates a good sourdough loaf with even crumb and a chewy but not tough crust. What you can't see is the flavour which I can tell you is delicious!
There is other techniques and methods with regular sourdough I would like to try with this process, that gluten free sourdough may still benefit from. 
So there will always be a jar with a starter living in it on my kitchen bench, ready to be used. I would like to know how everyone else gets on and what techniques you may try and the outcomes.
Now go, get started and dedicate some well worthy time to making your own gluten free sourdough bread!

Getting 'Started' To Make A Gluten Free Sourdough.

The first step in the sourdough process is getting a starter together. Gluten-free sourdough starter can be made in as little as seven days using gluten-free flour, water and a medium-sized bowl. I personally have successfully made gluten-free sourdough starter with sorghum flour, but I've read others have had success with buckwheat flour, teff, and millet.

Making a gluten-free sourdough starter isn't any different than making a regular sourdough starter.
  • Both start with flour and water.
  • Both take a few days and both get bubbly.
  • The only real difference comes when you're ready to make sourdough bread and you have to pull out all the various types of gluten-free flours.

Here’s a very simple explanation of the process:
  1. flour + water –> natural enzymes break down starches into glucose (sugar)
  2. natural bacteria (tang) + glucose = food for natural yeast
  3. natural yeast + food = carbon dioxide –> natural leaven
  4. natural leaven + more flour + more water –> more natural leaven
A good sourdough starter takes time and patience. Gluten free sourdough starter takes a little coaxing and a lot of patience. There are a lot of variables involved and if you are interested in making a gluten-free starter be prepared to make adjustments to account for the moods and whims for your particular starter.

Several things depends if your starter will thrive:

  • Temperature:  It is important to keep your starter in a warm place; if it gets too cold it won't be active enough to work.  Maintaining warm temps throughout the starter creation process helps to establish good yeast and bacterial multiplication and a healthy starter ecosystem.
  • Water:  Non-chlorinated water like filtered of spring is best for a sourdough culture. Tap water has been treated with chlorine for the nasty microorganisms lurking in the water supply. The chlorine also kills other microorganisms – the bacteria and yeasts you need to keep a lively starter. Using a filtering system removes the chlorine as well as heavy metals that can also damage the beneficial bacteria and wild yeasts present in a sourdough starter.
  • Flour properties: Any gluten free flour, provided it’s a grain-based flour, will work for making a sourdough starter. Keeping in mind it will be the bulk flour of what you bake with it, therefore the bulk flavor. Depending on what flour you use will deliver different results so bare that in mind and be prepared but don't be disappointed. 

Gluten Free Sourdough Starter

The Initial Starter:
Whisk 50g gluten free flour and 50g warm filtered or spring water in a small bowl. Pour this into a clean, sterilized glass jar. Cover with a cheesecloth securing it around with an elastic band and let sit for 12 hours at room temperature.

After 12 hours, whisk the starter and add 50g flour and 50g water. Cover and let sit for 12 hours at room temperature. Continue adding 50g flour and 50g water every 12 hours for up to a week. Your starter should start bubbling within a few days. As you feed your starter, take care to whisk in the flour and water thoroughly into the established starter – aerating the starter will help to yield the best and most reliable results.

The starter should be “spongy” in appearance with maybe some foamy bubbles on top and some air pockets in the mixture. It should have a slight sour smell. Your starter is now active and is ready to be used. If not needed immediately cover with cheesecloth and refrigerate.

Feeding Your Starter:
Once the starter is officially created, it enters maintenance mode. The frequency of feedings is determined by how much starter you need and how often you plan to use it.
  • At a minimum, the starter can be kept in the refrigerator and fed once a week merely to sustain life (the yeast).
  • You can continue to feed it daily as you have been, and in another seven days there will be enough starter for another batch of bread.
  • You can also feed it daily with as little as one tablespoon of flour and water – enough to continue daily growth but not produce a large quantity of starter.
However frequent or infrequent you decide to feed your starter, the yeast thrives best when it’s fed regularly and consistently.  Choose your time frame and quantity and stick with it as best as you can.

Using Your Starter:
Use your starter when it is active. An active starter is one that has been fed within the past 12 hours, and is active enough that it was able to double in size after that feeding. If you fed your starter and it didn't double, you should feed it a few more times before using. The best time to use the starter is somewhere between the time it reaches its peak and before it starts to fall.

Maintaining And Reviving Your Starter:
If you bake less than once a week, you can store your starter in the fridge and feed it once a week. When needed, remove starter from fridge and bring to room temperature. Feed and stir well to combine. Leave for 12 hours before you plan to bake. If you bake every day or a few times a week, you can store your starter at room temperature and feed it every 12 hours or twice a day to keep it alive. This is very important.

Try at least feeding the starter with as much flour as there is starter.  You don't need too much starter at a time, so for instance use 25g starter, 25g flour, and 25g water for the first feeding out of the fridge. The next feeding 12 hours later start with all of the starter from the previous feeding (75g), add 75g flour and 75g water.  You should see really large bubbles in the starter with this feeding schedule. When it's really bubbly bake with it. You will have 225g of starter to work with - that should be plenty. Just make sure you have at least 10g starter left when you're done to build up the new batch of starter.

Considerations For Your Starter:
Using a whisk helps to aerate the starter more thoroughly. Aeration of the starter is essential to ensure that the bacteria are well-distributed throughout the starter and can, begin to ferment the new flour and water added to the starter at each feeding.  Proper aeration of the sourdough also helps to ensure that the production of hooch – a thin liquid that sometimes rises to the top of sourdough starter – is minimized.

If a hooch does appear, don't worry, it is harmless. It often signifies that you've overfed your starter with water in relation to flour or have let your starter go too long between feedings. Sourdough starters are relatively resilient, and bounce back quickly once you resume proper care of them.

Do not ever cover your jar airtight. The mixture is harvesting the yeast from the environment and needs the air to breathe. Even while in the fridge. Furthermore, the process of fermentation releases carbon dioxide which can build up in a tightly lidded jar and explode. Remember your starter will expand and rise to twice its volume after a feeding once it’s well-established so the jar you choose should have double the capacity of an un-fed starter.

 The internet is filled with gluten free sourdough starter recipes. Some call for odd ingredients like pineapple juice, orange juice, cabbage leaves, grapes, potato flakes or water kefir, to make a truly good sourdough starter you need just three things: flour, water and time.

Gluten Free vs. Regular Sourdough.

When I looked into making gluten free sourdough bread I came across many sites claiming that regular sourdough bread is ok for celiacs and gluten intolerant people to eat. The explanation for this was the fermentation process breaks down gluten in sourdough breads made from wheat to levels that are safe for people with gluten intolerance to eat.

Investigating this further and found that a study performed by a group of researchers in Europe have discovered that "fully fermented" sourdough baked goods, made with a specialty wheat flour, did not have toxic effects on a small group of celiacs participating in the study. This wheat flour had been treated with lactobacilli, a "friendly" bacteria, and fungal proteases, a group of enzymes that break down (hydrolyze) the bonds that hold large protein molecules (gluten) together.

While the study was small, it did show that individuals with celiac disease who ate specially prepared sourdough wheat bread over the course of 60 days experienced no ill effects. The findings of this study and others like it are encouraging but larger studies are needed to confirm that specially treated wheat flour can be used to prepare safe baked goods for people with gluten intolerance and celiac disease. For now fermented sourdough bread prepared with ordinary, grocery store wheat flour and baker's yeast should not be eaten by celiac's and the gluten intolerant.

Researchers at the Department of Food Science, Food Technology and Nutrition in Ireland say, "The use of sourdough in gluten free baking may be the new frontier for improving the quality, safety and acceptability of gluten free bread." As explained in my last post, evidence is clear that sourdough is highly beneficial to gluten free health but the method of sourdough is also just as valuable towards the quality of gluten free bread.

Sourdough is the first fermentation used for baking purposes and it has been proven to be ideal for improving the texture, palatability, aroma, shelf life and nutritional value of wheat and rye breads. These effects have been extensively studied and well described for traditional baking, whereas little is known about the role of sourdough in gluten free baking. However, the microbiological and quality components of gluten free fermented products correspond in character with the microbiota of wheat/rye fermentation and suggest that the positive metabolic activities of the sourdough microbiota are still retained during fermentation of gluten free products. Thus, the use of sourdough in gluten free baking may be the new frontier for improving the quality, safety and acceptability of gluten free bread.

Making gluten-free sourdough bread is easy, once the principles and guidelines are understood. This type of baking is different from conventional gluten-free baking and is also different from conventional sourdough baking. There is a bit of a learning curve to this technique however many people have mastered it and are happily eating nutritious gluten-free sourdough bread.

With the sourdough technique and the right combining of gluten free flours, the all round quality of gluten free bread and nutrition can be achieved successfully. Until science establishes the safety of wheat-based sourdough for people with celiac disease, I think that long-fermented sourdough bread, made with gluten-free flours, represents the future of gluten-free bread for people with celiac disease and gluten-sensitivity by supplying enjoyment of eating top quality gluten free bread and aid in the healing of the digestive system.

Gluten Free Health Benefits from Sourdough.

Sourdough bread is made by a long fermentation of dough using naturally occurring yeasts and lactobacilli. Compared with regular breads, sourdough usually has a sour taste due to the lactic acid produced by the lactobacilli. Sourdough fermentation helps improve bread quality by prolonging shelf life, increasing loaf volume, delaying staling, as well as by improving bread flavor and nutritional properties.

Fermented foods have the ability to make food easier to digest as well as provide our bodies with needed nutrients and beneficial bacteria. Sourdough is one of those fermented foods. One of the ways to properly ferment grains (breads) is to use a sourdough method.

Sourdough breads are leavened by a starter that contain natural yeasts and acids. The airborne yeast creates the enzymes needed to eat up or predigest some of the toughest-on-your-belly parts of the grain. This action creates carbon dioxide, which gets trapped in tiny pockets of dough, resulting in a natural rising of the bread.

Like all other fermentation processes, the bacteria present in the sourdough starter eat the starch and sugars present in the grain. This results in a lowering of the starch or carbohydrate content of the bread, which is helpful for keeping blood sugar levels regulated. It also increases some of the vitamin and mineral content of the grain.

Sourdough performs the process of lactic acid fermentation that activates the phytase to hydrolyze (dissolve) the phytates, thus freeing up minerals such as: zinc, iron, magnesium, copper, and phosphorus. The lactic acid in the bread creates a lovely tang and predigests the grain for you. The acetic acid produced in the souring process helps the bread to store longer, inhibiting the growth of molds.

The bacteria present in the sourdough help to activate phytase, an enzyme that breaks down an anti-nutrient present in all grains, beans, and seeds – phytic acid. This may seem minor, but phytic acid is known to strip your body of minerals and can be hard on your digestion.

All in all, sourdough breads are much easier for the body to digest and as an added benefit, the bacteria also add nutrients into it as well.

However, sourdough isn't just good for making better bread. Recent studies show that sourdough fermentation can also speed gut healing in people with celiac disease at the start of a gluten-free diet. The longer soaking/rising time breaks the proteins (gluten) down into amino acids, making it more easily digested. This is why some who have a gluten sensitivity can tolerate sourdough wheat breads. Sourdough bread made with gluten-free flours might be the best way for people with celiac disease and gluten-sensitivity to get the benefits of sourdough cultures, and to enjoy fresh, minimally processed bread.
