I've made this twice, including last night:http://www.glutenfreecookingschool.com/archives/gluten-free-casein-free-flour-tortillas/
Super, duper easy. Pretty much fail-proof if you know how to roll out dough. I don't bother to use store-bought rice flour tortillas because they crack every time. These are a great alternative! And hold up great to my ridiculously overstuffed burritos.
