Pineapples are a tropical fruit that is exported and sold in supermarkets in western countries. Pineapples can be eaten raw or cooked to improve a stir fry.
Pineapples is a large fruit, it's too big for one person to eat at one sitting and after it's opened a pineapple deteriorates. This isn't a problem for a large family but for a small family or for someone living alone it's difficult. After you've started a pineapple you can always cut the remainder up and put it into the freezer. That way it won't get worse.
