Chana dal (also spelled “daal” or “dahl”) is an Indian comfort food. It is vegetarian legume dish that can be made thick or thin, depending on its role in the meal. It is served all over India, and every region has its own combination of seasonings, additions and level of spicy heat. This version leans toward the Northern Indian style and lacks the fiery heat and tartness of Southern versions. Just before serving, it is topped with a tadka ("tempering," in Hindi) of infused olive oil, garlic and whole spices.
