Wash the tripe in cold water until the water runs clear. In a bowl, rub the tripe with the lime juice and salt and allow to sit for about 1 hour. Wash again, dry the tripe, and cut into 1-in/3-cm dice.
Place the tripe in a stockpot, cover with water, bring to a boil, and simmer gently for 10 minutes. Drain the cooking liquid and discard.
