Add the psyllium husk powder and ½ cup lukewarm water to a small bowl and stir to combine.
Mix the yeast with the remaining ¼ cup of water and sugar and allow to rest for 10 minutes to activate the yeast. It will start to bubble when it’s ready.
Add the dry ingredients (flour, tapioca starch and salt) to a mixing bowl or stand mixer bowl. Stir and then add the activated yeast mix, psyllium mix, olive oil and apple cider vinegar.
Mix in the stand mixer or knead the dough until smooth and all the ingredients are well combined. The dough will be a little sticky at this point.
Turn out the dough onto a well floured parchment lined surface and, with oiled hands, gently knead and shape into a ball then cover with a clean tea towel or plastic wrap/cling film so it doesn’t dry out for 15 minutes.
Roll the dough into a circle using a rolling pin then press with your hands to stretch a little, rotating the dough, to ensure that it doesn’t stick to the surface. Form a 10 inch circle.
In the meantime, preheat the oven to 475F. Oil a pizza pan well, or large baking sheet and place in the oven until hot. Immediately transfer the pizza base off the parchment to the pan.
