If you are using active dry yeast, you need to activate it first. Mix the yeast with the lukewarm milk and one tablespoon of the sugar and set aside for 5-10 minutes. You will mix it later with the WET ingredients.
In a large bowl or the bowl of a stand mixer, whisk all the dry ingredients together: the tapioca starch, millet flour, sorghum flour, sugar, instant yeast (ONLY IF USING INSTANT YEAST), baking powder, xanthan gum and salt.
Make the psyllium gel: In a bowl, mix together the psyllium husk and lukewarm water. After about 30-45 seconds, a gel will form.
Add the milk, eggs and oil to the psyllium gel, and the yeast (ONLY IF YOU HAD TO ACTIVATE IT FIRST), mix well to combine.
Make a well in the middle of the dry ingredients and add all the wet ingredients.
Knead the dough until smooth and all the ingredients are evenly incorporated,I suggest using a stand mixer but you can do it by hand too.
If using a stand mixer, use a rubber spatula to occasionally scrape along the sides and bottom of the bowl to prevent any dry patches of unmixed flour.
Mix for 4-5 minutes.
The final dough will be sticky but don't worry, you'll be adding flour to the surface later so please don't add any more flour or water to your dough.
