Pick any dirt or stones from the dried chickpeas. Give it a quick rinse.
Take the black chickpeas in a large bowl or pot and add sufficient water. Cover and let it soak for 3-4 hours (you can also soak it overnight). Drain and rinse once soaked.
Instant Pot Method:
Add the soaked black chickpeas to the inner pot of the Instant Pot. Add two cups of water and salt. Secure the lid and pressure cook for 20 minutes. Do a natural pressure release for 10 minutes, then quickly release the remaining pressure manually.
If you are using unsoaked black chickpeas, add three cups of water and pressure cook for 50 minutes. Do a natural pressure release for 10 minutes, then quickly release the remaining pressure manually.
Stovetop:
Take soaked black chickpeas in a large pot and cover with several inches of water. Add salt and give it a quick stir.
Bring it to a boil and cover with a lid, leaving a small gap for the steam to escape. Simmer for 45-50 minutes or until they are done to your liking. Check once after 30 minutes to ensure there is sufficient water. For unsoaked kala chana, simmer for 1 to 1½ hours.
Notes
Don’t skip the soaking, as it significantly reduces cooking time and removes harmful substances from them. Aim for at least 3-4 hours, and if you are planning ahead, soak them overnight.
After soaking, rinse the beans thoroughly under cold running water.
Adding salt while boiling the black chickpeas will enhance their flavor.
