Tortillas, whether used to make tacos or as an accompaniment to an entrée, should be served hot. Chowhounds have some creative solutions for keeping them hot on a buffet table or taco bar.
hoosfoos likes the La Tortilla Loca Microwave Tortilla Warmer, which holds up to a dozen and keeps them warm for at least an hour. Bryan Pepperseed wraps tortillas in a damp cloth and puts the whole bundle in a slow cooker on the low setting.
HillJ has developed a technique that she says keeps tortillas “moist and warm for hours”: Wrap an electric heating pad in a bath towel, place it on the serving table, and plug it in. Park a platter of tortillas on the towel-wrapped heating pad, keeping the tortillas covered with a paper towel or napkin. HillJ uses the same setup for brunch buffets, and says it works equally well for waffles, French toast, and pancakes.
