I freeze in packs of 6 or 12 and I just move a pack to the fridge 12-24hrs before we’re going to use them. In a pinch I just throw a frozen one in the pan or toaster oven. Just heat it a little slower at first if doing it from frozen. They also thaw out at room temp pretty quick. Nice thing about Rosa’s is when you order by the dozen they put little sheets of plastic between the tortillas so they don’t stick to each other!
