Kala chana or black garbanzo bean is also known as Bengal gram in India. Grown in most temperate climatic regions of the world, these beans have a very distinctive flavor. Nuttier than garbanzo beans, these beans take longer to cook, denser in nutrition and hold shape when cooked. Although like garbanzo beans in protein and carbohydrate content, kala chana have higher iron and fiber content. Furthermore, they are also rich in micronutrients like iron, folic acid, sodium, and potassium. Soak beans either overnight or for 6 hours before cooking for best health benefits.
