Having problems with corn tortillas cracking. I've tried heating the tortilla using the following methods: 1) heating them in a pan on the stove. 2) leaving them in their bag and steaming them. 3) leaving them in their bag and microwaving them. ..still cracked What is the best way to heat a corn tortilla???? Also, I need to prep these in advance, place them in a half pan, top with shred cheese, covered with plastic, bring back to temp, and top with salsa. Considering the above, what do you think would be the BEST way to bring these back to temp? A steam? An auto shaam using steam and heat?
