Sambar is a traditional South Indian lentil-based curry made with toor dal, mixed vegetables, tamarind, and aromatic spices. It has a balanced flavor that is mildly spicy, tangy, and savory, enhanced by sambar powder and a tempering of mustard seeds, curry leaves, and dried red chilies. Sambar is commonly served hot as a side dish with idli, dosa, vada, rice, or paniyaram, making it a staple comfort food in South Indian cuisine.
