Here is a quick version of this traditional recipe. Normally, these beans are baked for hours in a stoneware pot, but using a pressure cooker is a great way to speed up the process, saving not only time but also a lot of electricity! (Unless you're in winter and the heat from the oven makes you save on the heating bill.) The Prep Time includes the soaking of the beans, and the Cook Time includes the depressurizing of the cooker. You can double the recipe, and it freezes and thaws very well. Serving size is for a main dish, maybe use a half or a third of the portion size for a side dish.
