Because refried black beans are so versatile and can be enjoyed plain or as a filling for enchiladas, tacos, burritos or omelets, they are a must in your stock of recipes. If youre cooking the beans from scratch, start with 1 1/2 cups dry beans; also, reserve 1 cup of the cooking liquid to use instead of the stock. Add a little water or stock to the beans when you rewarm them.
Heat oil in skillet over medium heat. Add onions, garlic and jalapeño, and cook, stirring often, over medium-low heat until onions are softened, 7 to 10 minutes. Add chili powder and cumin, and cook, stirring, 1 to 2 minutes, or until fragrant.
Increase heat to medium. Add 1 cup beans, 1/3 cup stock and salt. Using potato masher or back of spoon, mash beans into liquid. Continue cooking until liquid evaporates, 7 to 10 minutes. Add 1 more cup beans and 1/3 cup stock, and mash and cook again, stirring. Repeat, mashing and cooking and stirring, until liquid is absorbed and beans hold together, 8 to 10 minutes. Stir in lime juice, and adjust salt to taste.
