Can't Find Modified Tapioca Starch? in Gluten-Free Recipes & Cooking Tips Posted June 26, 2014 · Report to Admin Can you get Chebe crust mixes there? They are a tapioca based bread mix. You can use any of the breadstick, focaccia, or pizza dough mixes for a nice pizza crust. they call for cheese in the crust, but are good without. I pre- bake them to almost cooked before topping for pizza. http://www.chebe.com No I can get Bob's Red Mill mixes and a couple others. I was just excited to find recipes with such good reviews.
