سambar is a popular South Indian dish made from lentils and vegetables, cooked together with a unique blend of spices. It is typically served as a side dish with rice or idli, a type of steamed rice cake. The dish is known for its tangy flavor, which comes from the addition of tamarind. The main ingredients of sambar include toor dal (pigeon peas), assorted vegetables like carrots and eggplant, and a special spice mix called sambar powder. This nutritious dish is not only delicious but also rich in protein and fiber, making it a staple in many households across India.
