Heating: Tortillas may be heated on a skillet or electric griddle, on the grill, or in the microwave. For best results, heat tortillas on an ungreased skillet over medium-high heat for 10 to 15 seconds. Flip and heat for another 5 to 10 seconds. Microwave: Place 4 to 6 tortillas between two damp paper towels. Microwave 30 to 45 seconds or until heated through. Wrap in a cloth or tortilla keeper until ready to serve. For freshness, refrigerate after opening.
