Mollejitas

Mollejitas come out of the same thrifty Peruvian habit of cooking every part of the bird, and gizzards — cheap, plentiful, full of flavor — became a favorite. The dish is closely associated with the polleria, the rotisserie-chicken shop that spread across Peru from the mid-20th century, where gizzards are an everyday companion plate to pollo a la brasa. It is equally common as cheap home cooking and bar food. As a humble criollo preparation it carries no single inventor or fixed origin date.

Gizzards have a firm, satisfying chew — denser and springier than any other part of the chicken, almost like a tender clam — that holds up to long braising without falling apart. The tomato-onion sauce is tangy and savory, the aji a low warmth, and slow cooking leaves the gizzards yielding rather than tough. Rich, a little gamey, made for picking at with a toothpick and a drink.

The gizzard is a thick, collagen-rich grinding muscle, tough by nature, so the whole technique is slow moist heat: a long, gentle simmer hydrolyzes the collagen to gelatin and turns the muscle tender while keeping its characteristic bite. Cleaning is essential — the tough inner lining is trimmed away first. The tomato and onion break down into a sauce whose acidity further softens the meat, and the braise is held low so the gizzards never seize and toughen from a hard boil.
