I just thought I'd share a great tip I recently discovered for defrosting tortillas. I got a bunch of frozen tortillas from Mercado de México here in Munich and have been busy using them up. They separate from one another quite easily, then it's just a matter of heating them up. The easiest and best way I've found to heat them is to turn on one of the stove elements to high, throw a cookie cooling rack or oven grill on top of it, and just put the tortilla on that, flipping it once or twice until it's warm. Takes about 15 seconds.
I was so thrilled to figure out a way to do this that was simple, caused no washing up and left the tortillas non-soggy (unlike the microwave), I had to tell the rest of you.
