The name literally means 'tumbled-down rice,' a nod to how the dish is cooked loose and soupy rather than dry like most Mexican rice, closer to a seafood risotto than a side dish.
Rice is simmered directly with shrimp, octopus, or fish in a tomato-guajillo chile broth until it turns soft and soupy, then ladled into deep bowls. Market kitchens and portside food stalls across the port city of Veracruz serve it as a full meal.
