Michoacán, western Mexico — Uruapan and Quiroga in Michoacán are considered the spiritual homes of carnitas; the copper cazo tradition is unique to this region
Carnitas — 'little meats' — is the defining dish of Michoacán and one of the great slow-cooking techniques of the world. The process is disarmingly simple: pork is simmered in its own lard until the exterior crisps and caramelises while the interior remains moist and yielding. The result is simultaneously confit and deep-fried, and the technique produces textures impossible to achieve by any other method. The traditional vessel is a large copper cazo (cauldron), used throughout Michoacán. Copper's superior heat conductivity and the way it creates a slight acidity in the cooking fat are credited by Michoacán carnitas masters as contributing to the flavour. In a domestic kitchen, a large, heavy-bottomed pot or Dutch oven approximates the copper cazo adequately. The pork — ideally a combination of shoulder, belly, and ribs, all bone-in — is placed in the pot with enough lard to cover approximately halfway. Aromatics added to the lard vary by cook: most include Mexican Coca-Cola (its caramel colourings contribute to the final crust), fresh orange juice, dried oregano, and a small amount of milk or evaporated milk (which, controversially, contributes to browning). The fat is brought to a gentle simmer and the pork cooked, turned occasionally, for two to three hours. As the pork cooks, its own fat renders into the lard bath, and the moisture in the meat gradually evaporates. In the final 30 minutes, the heat is increased so the pork exterior fries properly in the now-enriched lard. The goal is pork that pulls apart effortlessly but has a crispy, golden-brown exterior on every exposed surface. Served chopped and assembled into corn tortillas with diced white onion, cilantro, salsa verde, and lime, carnitas is one of the simplest and most satisfying taco preparations in the Mexican canon.
Rich, fatty, and deeply caramelised — slow-rendered lard, orange and spice aromatics, with alternating crispy and yielding pork textures in each bite
Use a combination of pork cuts — shoulder for flavour, belly for fat, ribs for texture Maintain a gentle simmer rather than a rolling boil — the pork should poach in fat rather than fry from the start Increase heat in the final 30 minutes to achieve the characteristic crispy exterior Mexican Coca-Cola and orange juice are traditional flavour additions — both contribute to the caramelised crust Chop rather than shred for service — carnitas texture depends on distinct pieces with crispy and yielding sections in each bite
Evaporated milk added to the lard is controversial but traditional — it creates a more golden, crispier exterior through Maillard reactions with milk solids The spent carnitas lard, strained and refrigerated, is extraordinary for frying beans and eggs For smaller batches, a cast-iron Dutch oven with enough lard to come halfway up the pork works well Rest the finished carnitas on a wire rack to allow steam to escape rather than softening the crust For service, press the chopped carnitas briefly onto a very hot comal to re-crisp any sections that have softened
Using only lean pork shoulder, which produces meat too dry for proper carnitas Cooking at too high a temperature throughout, frying the exterior before the interior is fully tender Skipping the final high-heat crisping stage, serving soft rather than properly textured carnitas Shredding carnitas as you would pulled pork — the rough chop is essential to maintain textural variety Using vegetable oil rather than lard, which produces a different flavour profile and inferior crisping
