Gulupa belongs to the flowers of passion family. Its name derives from the particular shape of its flower. This fruit is round, and it has a soft, edible skin that wilts when the fruit is ripe. Its pulp is gelatinous with many edible seeds and has a slightly acidic taste.
Native to Brazil, the gulupa is grown in many tropical regions. There are about 400 different varieties of this plant, of which only about thirty produce edible fruits. Only few of them come to our markets.
