Cooks judge the dish ready not by a timer but by smell — the tripe must simmer in ají color until the kitchen smells like a spice market, a test passed down orally between market cooks.
Diced beef tripe is stewed with potatoes, onion, and a deep-red ají sauce until thick enough to eat with a spoon and bread. It's sold by the bowl at northern Chile's covered markets, usually alongside rice.
