Pre-independence Kerala was split into the princely states of Travancore and Kochi in the south, and the Malabar district in the north; the erstwhile split is reflected in the recipes and cooking style of each area. Both Travancore and Malabar cuisine consists of a variety of vegetarian dishes using many vegetables and fruits that are not commonly used in curries elsewhere in India including plantains, bitter gourd ('paavaykka'), taro ('chena'), Colocasia ('chembu'), Ash gourd ('kumbalanga'), etc. However, their style of preparation and names of the prepares dishes may vary. Malabar has an array of vegetarian and non-vegetarian dishes such as pathiri (a sort of rice-based pancake, at times paired with a meat curry), porotta (a layered flatbread, said to come from South-East Asia), and the kerala variant of the popular biriyani, probably from Arab lands. Central Travancore region boasts of a parade of dishes that is largely identified with the Christians of the region.

In addition to historical diversity, the cultural influences, particularly the large percentages of Muslims and Syrian Christians (also see Syrian Christian Cuisine of Kerala) have also contributed unique dishes and styles to Kerala cuisine, especially non-vegetarian dishes. The meat eating habit of the people have been historically limited by religious taboos. Brahmins eschew non vegetarian items and Hindus historically do not eat beef. However, most of modern day Hindus do not observe any dietary taboos, except a few of those belonging to upper caste (Nambudiris, Nairs of Malabar). Muslims do not eat pork and other items forbidden by Islamic law.

Historically, Kerala had been a part of the Tamil-speaking area, and Tamilian influence is seen in the popularity of sambar, idli and dosa. European influence is reflected in the numerous bakeries selling cakes, cream horns, and Western-style yeast-leavened bread, and in Anglo-Indian cuisine. The import of potatoes, tomatoes, and chili peppers from the Americas led to their enthusiastic use in Kerala, although except for the ubiquitous peppers, the other ingredients are used more sparingly.
