Geographical and cultural influence on the regions cuisine: South India has hot, humid climate and all its states are coastal. Rainfall is abundant and so is the supply of fresh fruit, vegetables and rice. Andhra Pradesh produces fiery Andhra cuisine which is largely vegetarian yet has a huge range of seafood in the its coastal areas.
Tamilnadu has Chettinad cuisine, perhaps the most fiery of all Indian food. This style too is largely vegetarian.

Rice is combined with Sambaar (a soup-like lentil dish tempered with whole spices and chillies) and rasam (a hot-sour soup like lentil dish), dry and curried vegetables and meat dishes and a host of coconut-based chutneys and poppadums (deep-fried crispy lentil pancakes). South Indians are great lovers of filter coffee.
Staple foods: No South Indian meal is complete without rice in some form or other either boiled rice or Idlis (steamed cakes made from rice batter), Dosas or Uttapams (pancakes made from a batter of rice and lentil flour).
Daals (lentils) are also a part of most meals.
