Fried plantains are popular across the Caribbean, South America and Central America. Like the bananas they resemble, they are naturally sweet and rich in potassium, however they are much more savory and are a suitable substitute for a starch, like rice or potatoes. The plantain develops a beautiful caramel when it's fried, making it the perfect side to balance out a flavorful main dish, like spicy jerk chicken or ropa vieja.
