The food history of North Goa is deeply influenced by its coastal setting, Hindu origins, and centuries of Portuguese colonialism. The staple diet of the Goan population historically has been fish curry and rice. Goan cuisine is a blend of different influences the Goans had to endure during centuries of rule. The Saraswat Brahmins and the Konkanis were the first communities to inhabit Goa and they brought with them plantain, fish, and coconut-based dishes that are still popular. Spices were introduced by the Arab traders and became essential for enhancing the flavors in dishes. The Portuguese arrived in the 16th century and introduced new types of food such as potatoes, tomatoes, pineapples, guavas, and cashews from Brazil (which is actually not native to Goa). The Portuguese equally influenced the culinary scene by introducing vinegar, which is used in the preparation of Vindalho, a Portuguese derived dish from "Vinho de Alho".
