Kidney beans are beans that when dried have a shape suggested of a kidney, though the shape disappears when cooked.
They are about 2 cm (1/2 inch) long.
They come in red and white varieties. See separate entries on each.
Cooking Tips
Both varieties have a creamy texture when cooked.
They need about 3 hours of boiling if unsoaked, closer to 2 if soaked before cooking.
Rinse canned ones in a sieve under running water to remove sludge and some excess sodium off them.
