Here's what I did:
Ingredients:
2 1/2 cups unbleached flour
1/2 cup whole wheat flour
1 1/2 tsp salt
1 tsp baking powder
2 TBL vegetable oil
2 TBL butter, cut into small pieces
1 1/4 cups warm water
Directions:
In a mixing bowl, mix flours, salt, and baking powder. Add oil and butter and mix with a pastry blender or just use your hands. Mix till butter is well blended into the flour. Add the water, slowly, and mix with a fork. **NOTE** I only needed 1 1/8 ish cups water. Depending on where you live and the humidity level, you may not need all 1 1/4 cups water. Once the dough has come together, knead for a couple of minutes. Form a ball with the dough, cover with a damp towel and let it rest for 30 minutes. The dough should be pliable, but not sticky.
Divide the dough into 12 pieces and form each one into a ball. Cover with a damp towel and let the dough rest again for 20 minutes.
Heat a heavy pan (a cast iron skillet would be perfect!) over med-high heat. While pan is heating, roll out one ball of dough at a time with a rolling pin to the desired thickness you like. I made some small and some big tortillas, but made them very thin. Cook for about a minute on each side till bubbly and browned. Flip and cook another minute or so. Here's what I did different. While cooking in the pan, I set a smaller pan on top of the tortilla so it would brown more evenly and not bubble up.
That's it! I froze mine and put sheets of wax paper in between. I got 16 out of this batch. If you will be eating right away, keep covered with a towel to keep them warm!
