Puerto Rico, a Caribbean island rich in history and remarkable natural beauty, has a cuisine all its own. Immigration to the island has helped to shape its cuisine, with people from all over the world making various contributions to it. However, before the arrival of these immigrants, the Taino people lived on the island of Puerto Rico. Taino cuisine included such foods as rodents fresh shellfish and fish fried in corn oil.
Many aspects of Taino cuisine continue today in Puerto Rican cooking, but it has been heavily influenced by the Spanish, who invaded Puerto Rico in 1508, and Africans, who were initially brought to Puerto Rico to work as slaves. Taino cooking styles were mixed with ideas brought by the Spanish and Africans to create new dishes. The Spanish extended food choices by bringing cattle, pigs, goats, and sheep to the island. Africans also added to the island’s food culture by introducing powerful, contrasting tastes in dishes. In fact, much of the food Puerto Rico is now famous for—coffee, coconuts, and oranges—was actually imported by foreigners to the island.
波多黎各是加勒比海地区的一个岛屿，历史悠久，自然风光优美，具有风味独特的菜肴。来自世界各地的移民为菜肴的形成贡献了力量，帮助这里形成了自己的烹饪风格。然而，移民到来之前，泰诺人生活在波多黎各岛，他们的菜肴包括啮齿动物、新鲜贝类和玉米油炸鱼。
今天泰诺人的烹饪方式还存在于波多黎各人的烹饪中，但是深受1508年入侵当地的西班牙人影响，同时还受到被带到这里做奴隶的非洲人的影响。泰诺人的烹调风格与西班牙人和非洲人的烹饪想法融合在一起，进而形成了新的菜肴。西班牙人带来了牛、猪和羊，从而增加了食材的范围，非洲人使菜肴的口感强烈，对比鲜明，增加了这里的食品文化。事实上，波多黎各的很多食物以咖啡、椰子和橘子闻名，而这些都是外国人带来的。
