In a large bowl, stir flours, salt and baking powder. With a pastry cutter

blend in shortening until resembles coarse meal. Add enough hot water to form a stiff dough. Place dough on plastic wrap and form into a cylinder, approximately 2 1/2 inches thick. Refrigerate at least 1/2 hour. ( dough can be made up a day in advance). Cut dough into 12 pieces. Form each into a ball. On floured surface, roll each ball into flat 8-inch circle. Cook on hot ungreased griddle or skillet until lightly browned, about 30 seconds. Turn to other side and cook 20 seconds.

I have made the flour tortillas without shortening and they were just fine. I made no other adjustments to the rest of the recipe.
