Soak the chana dal for at least 6 hours. Drain, rinse and cook it either in a pot on the stove, in a slow cooker or in a pressure cooker. Drain.
Purée the chana dal and garlic in the bowl of a food processor and process until blended. Add the tahini, lemon juice and salt and process until the hummus is creamy. Adjust to taste if necessary.
Store in a glass jar or container in the refrigerator for up to at least a week.
Notes
Save any of the cooking broth from the chana dal. Refrigerate or freeze it to cook with later. Cook more beans or lentils in the broth or use it to thicken soups, season and drink like bone broth or add to quick breads and doughs.
