Prolly the biggest difference is the maker. Corn tortillas from the store here? Slapping them in a dry comal (or dry anything) gives you something akin to sheetrock. (Might as well use them for that, as you won't be eating them.) Alynne is in WDC so may or may not have access to better tortillas. When I get them from the store, reheating method depends on how much time and effort I'm willing to put in. Sometimes I'll wrap them in paper towels and nuke them. That's ok for 3 or 4, but doesn't give good results for more than that.
