Pineapples can be used raw or cooked. To prepare the pineapple for use, cut off the top and the base, stand the pineapple upright and slice away the skin in a downward vertical motion. The core can be left in or removed depending on preference, though it is edible, and can even be pressed for juice. Raw pineapple can be eaten as is, and also juiced or pureed for smoothies and fruit cocktails, like a pina colada. Fresh pineapple can be roasted, grilled, or baked for desserts, including pineapple upside-down cake. It can also be cooked and sweetened as a topping for custards and cheesecakes. Try dicing and pairing fresh pineapple with tomato, herbs and chilies for a salsa to accompany seafood. The enzyme, bromelain, contained in pineapples helps break down proteins, and hence pineapple juice is often used as a marinade for meats, especially pork.
Fresh pineapple is highly perishable, and if kept at room temperature it should be eaten within a couple days. Store in the refrigerator to extend its shelf life up to 5 days. Fresh, cut pineapple can be covered in its natural juice and stored in an airtight container in the refrigerator for 5 to 7 days, or frozen for up to about 6 months.
