Stir together first 4 ingredients. Cover and chill until ready to serve.
Bring 2 cups water and salt to a boil in a Dutch oven over medium-high heat. Add pork; reduce heat to medium low, and cook 1 hour and 15 minutes or until water evaporates. (Meat will look pale.) Cook, stirring occasionally, 10 more minutes or until pork cubes are golden brown. Drain on layers of paper towels. Serve with garlic mixture and lime wedges.
