Eat & Drinks

The Puerto Rican cuisine is very varied. It has been influenced by Indian, African and, of course, Spanish traditions. The Spanish influence is expressed in dishes with stewed meat (pork or beef), wheat, rice and beans with olive oil and other oils. African features involve herbs, spices and exotic ingredients, such as okra and taro. As a result there is a unique and distinctive blend of cooking traditions with plenty of wonderful dishes. Try sancocho — beef stewed with vegetables, ternera la parmesana — veal with Parmesan, lechon asado — barbecued pork with roast bananas, and pollo al jerez — poultry stewed in sherry. Tap water is dangerous, so it is better to buy bottled water.
