There are few things worse than pulling some tortillas out of the refrigerator, peeling one off the top of the stack, and watching it split into pieces. A split tortilla is no good to anyone, so you try to surgically remove it one quarter inch at a time. Eventually you accept that the tortilla is ruined, and what was going to be a taco, burrito or fajita has transformed into a mess of meat, bread and sauce that you have to eat with a fork. Happily, there's a way to avoid this. All you have to do is warm up the tortillas first.
Run a little it of water over a dish towel. Ensure that the whole towel has some water on it.
Squeeze the towel so it's just a little damp.
Wrap the tortilla stack in the towel.
Put the wrapped tortilla stack in the microwave.
Set the microwave for around two minutes.
Check the tortillas regularly to make sure they are warm enough to stay in one piece.
