The kidney bean is a variety of the common bean (Phaseolus vulgaris). It is named for its visual resemblance in shape and colour to a kidney. Red kidney beans should not be confused with other red beans, such as adzuki beans.

Dishes
Red kidney beans are commonly used in chili con carne and are an integral part of the cuisine in northern regions of India, where the beans are known as rajma and are used in a dish of the same name. Red kidney beans are used in New Orleans and much of southern Louisiana for the classic Monday Creole dish of red beans and rice. The smaller, darker red beans are also used, particularly in Louisiana families with a recent Caribbean heritage. Small kidney beans used in La Rioja, Spain, are called caparrones. In the Netherlands and Indonesia, kidney beans are usually served as soup called brenebon. In the Levant a common dish consisting of kidney bean stew usually served with rice is known as fasoulia.
Bean Paste
Kidney beans are generally prepared from dried beans and boiling until they are soft. Kidney beans are dark red in color when they are whole cooked. Kidney bean paste can be made by cooking and pulverizing the beans to a dry paste.
Toxicity
Raw kidney beans contain relatively high amounts of phytohemagglutinin, and thus are more toxic than most other bean varieties if not pre-soaked and subsequently heated to the boiling point for at least 10 minutes. The US Food and Drug Administration recommends boiling for 30 minutes to ensure they reach a sufficient temperature long enough to completely destroy the toxin. Cooking at the lower temperature of 80 °C (176 °F), such as in a slow cooker, can increase this danger and raise the toxin concentration up to fivefold. Canned red kidney beans, though, are safe to use immediately.
