If you're looking to add some variety to your fruit bowl, consider red bananas. They're available year-round in supermarkets and specialty stores. Use them as you would yellow bananas -- eating them raw, slicing them into fruit salads or baking or frying them. While tasty, these purplish bananas are also nutritious, providing you with vitamins and minerals as well as fiber.

Comparison

Compared with yellow bananas, the bananas most often seen in U.S. markets, red bananas tend to be smaller. Their peel is a deep red, maroon or purple hue and their flesh is a creamy whitish-pink that often tastes of not just banana but raspberry. Nutritionally, both yellow and red bananas are valuable fruits.

At the market, look for bunches of red bananas that are fairly firm, with no bruises, breaks or blemishes visible on the peel. Bananas with a deep purple color are ripe. Grocers in the United States often import their red bananas from Costa Rica.

Storage

Once you bring them home, leave red bananas out at room temperature to ripen, if need be. Turn them occasionally. Do not cover or refrigerate them.
