Tacos de Suadero

Los tacos de suadero are a defining street food of Mexico City. Suadero (the cut from the upper leg of the cow, between the brisket and the flank) is a fatty cut that, when slow-cooked in its own fat (a confit technique), becomes meltingly tender. The preparation technique is reported to have origins in Mexico City's old street markets, particularly the famous La Merced market. The tacos are sold from taquerías, street carts (taqueros), and market stalls across Mexico City, particularly popular as an evening street food. The chopping of the cooked meat and the small tortilla format are characteristic of Mexico City-style tacos.

A taco de suadero presents a small double-stacked corn tortilla filled with chopped, meltingly tender fatty beef, topped with chopped onion and cilantro. The first bite is rich and beefy — the suadero's fat has rendered during the long confit, giving the meat a melting texture; the onion adds crunch; the cilantro adds freshness. Eaten with salsa, two or three per serving, often with a slice of lime and a radish.

Tacos de suadero's melting texture depends on the confit cooking. Suadero (a fatty cut) is cooked slowly in a large pan of hot fat (its own rendered fat, plus lard) at low temperature (around 100-110°C) for 2-3 hours. The fat conducts heat evenly and prevents the meat from drying out; the low temperature allows the collagen (which is abundant in this cut) to denature into gelatin slowly, making the meat meltingly tender. The meat's external fat renders into the cooking fat, contributing its own richness. After cooking, the meat is chopped (rather than sliced) to expose more surface area for the toppings; the small double-stacked tortillas provide structural strength against the juicy filling.
