First, warm the nut milk until 110-115 F. (I highly suggest weighing your flours).
Second, warm the milk up in the microwave for 30 to 40 seconds.
3/4 cup nut milk of choice
Third, proof the yeast to make sure it is good.
In a mixing bowl of a stand mixer combine the yeast, olive oil, and maple syrup stir until combined.
1 1/2 tsp active dry yeast, 2 tsp olive oil, 2 tsp maple syrup
Next, add the warm nut milk to the yeast mixture.
All the mixture to sit for 10 minutes.
When it gets bubbly and frothy that means the yeast is good and you can continue.
Combine the cassava flour, tapioca flour, potato starch, psyllium husk powder, onion powder, and salt in a separate bowl.
1 cup cassava flour (120 grams), 1/2 cup tapioca flour (60 grams), 1/3 cup potato flour, 2 tsp psyllium husks powder, 1/2 tsp onion powder, 1/2 tsp pink salt
Stir until combined.
Finally, pour the flour mixture into the yeast mixture.
Add in the olive oil.
Add the dough hook to the mixer and knead for 3 minutes.
Form into a ball.
Grease a bowl place the dough hook in and allow it to rise.
Allow to rise for one hour.
It will rise slightly but not like bread with gluten.
