I do make these from memory, but it's not usually a problem. I definitely don't use 1/2 c. oil. I just a couple tablespoons at best...and I do use 3 c. white and 3 c. wheat flour. Sorry about that folks. Happy tortilla making!
6 c. flour
1 t. salt
2 c. hot water
1/2 c. oil
Separate dough into individual balls. Roll out to desired thickness. Cook on hot skillet. When dough begins to bubble, flip over. Cook an additional 10-30 seconds.
