问答题Practice 1 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.
