ABOUT THIS RECIPEA hearty tortilla with room for contrast
Tlayudas are closely associated with Oaxaca, in southern Mexico. They’re made with a large, thin corn tortilla cooked on a hot griddle until firm and crisp, but not so dry that it breaks with the first bite. In this version, black beans, asiento, cabbage, quesillo and salsa make a complete meal. The large tortilla is easy to share; you can also serve smaller ones individually.
Asiento is the seasoned, soft sediment left over from rendering pork fat, and in Oaxaca it’s used as a spreadable seasoning. It gives the beans a savory, full-bodied base. Asiento isn’t available everywhere; a thin layer of lard is a practical substitute, though it has a less distinctive flavor. For a version without animal fat, you can use neutral oil. The black beans remain important: mash them roughly so they’re easy to spread but still have some texture.
Quesillo, also known as Oaxaca cheese, is a fresh cheese that pulls apart into strings when warmed. Its mild, milky character softens the beans and fat. If you can’t find quesillo, mozzarella works as a practical substitute. It isn’t the traditional ingredient and the flavor is different, but it melts well. Use low-moisture mozzarella and pat a very wet variety dry first; otherwise, the tortilla can turn soft.
The cabbage isn’t just decoration: very thin strips add a cool, crisp bite against the warm, soft cheese and beans. White cabbage is firm and easy to slice; pointed cabbage works too, but wilts faster. The tomato salsa gets its flavor from briefly roasting the tomato, garlic and dried chili before chopping them finely. Adjust the amount of chili to your preference and keep the salsa fairly thick so it doesn’t run off the tortilla.
A heavy skillet or cast-iron griddle works well at home if you don’t have a comal. Heat it thoroughly first and cook the tortillas without oil so they dry and brown evenly. Then top them sparingly and heat briefly, until the cheese is soft. The edge can be crisp, while the center stays pliable from the beans and toppings. Serve right away, with extra salsa if you like. Store leftover beans and salsa covered in the refrigerator; top the tortillas just before eating so they don’t turn soggy.
