Best Pizza Crust

Originally found at recipezaar.com
Finally a crust that is crispy on the bottom and has a chewy crust and no funky taste. I don't know how well it reheats...we ate the whole pizza!
Ingredients
1 tablespoon dry yeast
2/3 cup brown rice flour or gram flour or fava bean flour(I use 'garfava' flour which is a blend) or combination
1/2 cup tapioca flour
2 tablespoons powdered milk or non-dairy powdered coffee creamer(Dairy alternative, 2 T tapioca flour or sweet rice flour in place of 2 T dry milk powder or non-dair)
2 teaspoons xanthan gum
1/2 teaspoon salt
1 teaspoon unflavored gelatin
1 teaspoon italian seasoning
2/3 cup water(110 degrees F)
1/2 teaspoon sugar or honey or agave syrup
1 teaspoon olive oil
1 teaspoon cider vinegar
Directions
1Preheat oven to 425 degrees F.
2In medium bowl using regular beaters (not dough hooks), blend all ingredients on low speed.
3Beat on high speed for 3 minutes.
4(If mixer bounces around bowl, dough is too stiff. Add water if necessary, one tablespoon at a time, until dough does not resist beaters.) Dough will resemble soft bread dough.
5Put mixture on lightly greased 12-inch pizza pan or 11 x 7-inch pan (for deep dish version).
6Liberally sprinkle rice flour on dough, then press dough into pan, continuing to sprinkle with flour to prevent sticking to hands.
7Make edges slightly thicker to hold toppings.
8Bake pizza crust for 10 minutes.
9Remove from oven.
