Red Beans

As their name suggests, red beans are red beans. They are small, plump, and oval-shaped. Small red beans resemble kidney beans, but they are smaller and more rounded. They are about a 1/2 inch in length. Red beans are similar to and often confused with Adzuki beans, commonly grown throughout East Asia.

Kidney Beans

Kidney beans come in a variety of colors and patterns. Kidney beans get their name because they are said to have a similar shape to the kidney organ in the human body. There are four main types of kidney beans, red kidney beans, light speckled kidney beans, red speckled kidney beans, and white kidney beans also known as cannellini beans.

Dark red kidney beans look similar in color to red beans; however, kidney beans are larger in size and have a kidney shape.

Kidney beans can be used in various dishes, such as chili recipes, refried beans, soups, and salads. They are usually eaten well cooked as improperly cooked or raw kidney beans are toxic.

It is recommended that kidney beans are pre-soaked and boiled for 30 minutes to destroy the toxin phytohemagglutinin they contain. Kidney beans are best cooked on a stovetop or in a pressure cooker, as cooking kidney beans in a slow cooker is not recommended as the temperature will not be high enough to destroy the toxin.
