Also Known as
Kidney beans, red kidney beans
Just as its name suggests, the kidney bean is shaped like a kidney with a reddish brown colour and a thick skin. It has a strong flavour with a slightly sweet aftertaste, a nutty aroma and a chewy texture. The kidney bean is used extensively in Mexican cooking, and also in certain Indian dishes. It is quite popular in Punjabi cuisine.
Dark red kidney beans hold their shape really well during cooking and readily absorb flavours, making them a favourite addition to simmered dishes. Small and big sized beans are available, and you can choose what suits your recipe.
Black kidney beans and others such as pinto beans, navy beans, etc., are often referred to as ‘common beans’ in many countries. Black rajma is also available small and big, so choose what fits your recipe.
Boiled and crushed rajma
Wash and soak the rajma overnight. Then, drain and rinse the beans. Add soaked beans and water to a pressure cooker. The water should top the beans by about 2". Lock in the lid. Turn on heat. Cook for 15 minutes. Turn off the flame. Wait till the pressure has dropped, then open and drain the excess water. Let it cook a little. Take a potato masher and mash the rajmato get the desired smoothness.

Rajma may also be cooked in a pot. Place soaked rajma in a pot and cover completely with water. Add salt to taste. Cook it with a lid on. Once done, remove from heat and drain the water. The cooking time will vary depending on method, quantity, quality and age of beans.
Boiled rajma can be eaten hot, warm or cold, as per one's choice, in various recipes.
To soak rajma beans, first wash them thoroughly, check for any stones and then soak in warm water. It is better to change the water from time to time while you're soaking or cooking the beans. Pouring off the water helps gets rid of the indigestible complex sugars that create gas in your intestine. It also helps to cook the beans thoroughly, until they can be easily mashed with a fork.
Store soaked rajma in the refrigerator in an airtight container and use within 2 to 3 days. Longer storage could cause an undesirable odour.
Soaking rajma does not cause any nutrient loss but makes it easier to digest. Soaking before use is recommended for those with gastric troubles.
After soaking rajma overnight, cover it with a muslin cloth or cheese cloth. Place this in a warm area to induce germination. Once germination begins, the sprouts will begin to grow. Ensure that you keep changing the water. Within 24 to 26 hours, small edible shoots begin to appear. Always wash gently and then use in the recipe. Ensure that you don't expose these sprouts to sunlight.
