Breadfruit (Artocarpus altilis) is the large, round, starchy fruit of a fast-growing tropical tree in the mulberry and jackfruit family. Picked mature but unripe, it is a staple carbohydrate across the Pacific, the Caribbean and the tropics — cooked like a potato by roasting, boiling, baking or frying, with a bland, bready, faintly sweet flesh that gives the fruit its name.
