For this vegan gluten free cracker recipe I wanted to get a crispy, flaky texture which is not easy. So I needed to use a few gluten free starchy flours like cassava flour and white rice.

For extra fibre and flakiness I incorporated some tigernut flour (use extra fine almond flour as a substitute). Then the oil and water are bringing the necessary moisture to the gluten free dough, resulting in a perfect balance that make these vegan gluten free sourdough crackers easy to roll out.

- To form the dough you simply combine all dry ingredients (the flours, psyllium husk, ground flax seeds, salt, maple crystals) then add: the gluten free sourdough starter, oil and water. Mix well.
- Then add the baking soda + lemon juice, it will enhance the dough with air pockets and bring flakiness. If you skip this step the crackers will have a more sturdy, hardened texture.
- Place the ball of dough between two pieces of parchment and using a rolling pin, roll until very thin, about 1/8 inch thick.

4. Then once the dough is formed, sprinkle with seeds and slice. And in 20 minutes you get tasty, crispy vegan gluten free sourdough crackers!

Hi. Recipe looks great. Can O use Sorghum flour instead of all the other flours used in this.
Sorghum flour is a whole grain flour, for most recipes it cannot be used solely as a direct replacement for wheat flour. Whole grain flours are lacking in the necessary stickiness to keep baked goods together, or you will get a dry and crumbly texture. This is the reason you will need to combine three or more flours to achieve structure, lightness and good flavor especially for pastries.
You should make this post like into a definitive guide or something. I bet a lot of your new readers that come to this site would want to be able to find this post. It’s too good to keep secret!
Can you use yogurt instead of sour dough starter? I’m not sure if anyone tried yogurt but I was just wondering
That’s an interesting question, I never tried that. I think it depends what kind of bacterial strains are in there, how many and how strong they are. Plus you will definitely need yeast to make it rise.
I could eat the entire tray of these delectable crackers. I subbed buckwheat for tigernut as that’s what I had on hand. I’ve made crackers before that tasted okay but they were too hard for my liking. These are great. Thanks.
I’m really glad you enjoyed them 🙂 !
