Plantains are native to India and are grown most widely in tropical climates. Plantains are sometimes referred to as the pasta and potatoes of the Caribbean. Sold in the fresh produce section of the supermarket, they usually resemble green bananas but ripe plantains may be black in color. This vegetable-banana can be eaten and tastes different at every stage of development. The interior color of the fruit will remain creamy, yellowish or lightly pink. When the peel is green to yellow, the flavor of the flesh is bland and its texture is starchy. As the peel changes to brown or black, it has a sweeter flavor and more of a banana aroma, but still keeps a firm shape when cooked.
