Canned white kidney beans, also known as cannellini beans, are large, oval-shaped legumes with a smooth, creamy texture and a mild, nutty flavour. Typically packed in water or brine for preservation, these beans are ready to use straight from the can. They have a pale, off-white color and hold their shape well during cooking. They can be used in a variety of dishes, including soups, stews, salads, and pasta dishes.
