Okra originates from Europe and Asia but is most commonly cultivated in the tropics and subtropics of the Americas. Only the fruit of the okra plant is eaten. As a vegetable, okra has a variety of preparation methods. Due to a high amount of a gelatinous substance, okra is also often used as a thickener for broths and soups. In some countries the seeds are used as a substitute for coffee.
