The kidney bean otherwise called 'the chilli bean' with its dark red skin is named for its visual resemblance to a kidney. The kidney bean is also known as the red bean, although this usage can cause confusion with other red beans. Red kidney beans (rajma in Hindi and Punjabi) are an integral part of the cuisine in northern region of India. Red kidney beans are universally 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. Some say they have a smoother taste. Small kidney beans used in La Rioja, Spain, are called Caparrones. Uses: Most often used in thick soups or with rice; basic for many Mexican, Caribbean and Latin American soups and side dishes.
