El Milagro whole wheat tortillas are the best quality tortillas made. When our tortillas are heated they get just as soft as when they were freshly baked. Directions Refrigerate after opening. How to Heat: Our tortillas are fully cooked, just heat them. Put the tortilla one at a time on any dry hot pan or skillet (med. heat). Turn every few seconds until hot: do the same until you have as many as you need. Wrap hot tortillas in a clean kitchen towel to keep them hot throughout your meal.
