Pongal is a rice pudding that is usually eaten during special or ceremonial occasions in Southern India and Sri Lanka. It is usually cooked in a clay pot over an open fire. Milk and water are boiled first, and according to Tamil beliefs, if the liquid spills over the pot it will bring good luck and prosperity to the family.
The preparation of pongal is a family affair because each family member ceremonially adds a handful of rice to the pot. Subsequently, remaining rice is added to the dish with sweet (sakkarai) or savory (ven) ingredients. Pongal is served on banana leaves, and before it is consumed the entire family says their prayers to the Sun god.
If there is any pongal left, it is usually shared with friends and relatives. The dish originated among the Sri Lankan Tamil ethnicity and the name of the dish is derived from Thai Pongal, a festival celebrated on January 14th, symbolizing the end of the harvest season, the Tamil equivalent to Thanksgiving.
