My sister-in-law is the coolest. When I visited a few weeks ago, she made tortillas. They were yummmmy! If you want to make them too, it's really easy. Go here for the recipe for step-by-step details and pictures.
For the 1/2 c oil, I used 1/4 c coconut oil + 1/8 c sesame oil + 1/8 c olive oil. My friend Rachael recommended squishing the dough ball with another cutting board. Worked like a charm.
You can see that I covered the dough with a dish towel. The next time, I'll cover it with plastic or wax paper. I forgot that I live in the desert and it's dry here.
In the beginning, I used the rolling pin in the picture. After about 20 tortillas, I switched to a French rolling pin (or a really fat dowel rod) and it was much easier on my wrist.
