Banana flowers are often used as a vegetable in stews and soups in Asian cuisine. This banana plant originally comes from the Andes mountains of Colombia. The banana flower is a large, dark purple to red flower, from which bananas normally grow. The flower is composed of several layers of leaves, which curl up one by one to give the small internal flowers the chance to develop into bananas. The taste of this edible flower is mild and slightly bitter. These banana flowers are preserved in salt water to extend their shelf life. They can be used as part of a main dish or side dish.
