Cannellini Beans are large white Italian kidney beans available both dried and canned. Dried beans should be soaked overnight, then boiled for 10 minutes, then reduce the heat and simmer for about 1-2 hours or until tender. This bean should be salted after to cooking to avoid toughing the bean. Some brands of canned beans are much better than others. Eden foods produces a tender, creamy bean product.
Find cannelini in most well-stocked grocery stores. Eden brand canned beans are typically available at Whole Foods and other health food stores. You can purchase them online at Walmart as well.
