The Gulupa, also known as Purple Passion Fruit, belongs to the Passiflora family, just as Granadilla and Maracuya (Yellow Passion Fruit). Its hard skin ranges from green/purple to reddish/brown. The gelatinous pulp is of an intense orange color with a fresh, slightly acidic flavor, and it contains black edible seeds.
We will know if the passion fruit is ripe because the skin creases a little. Fruits with a harder, smooth skin can also be consumed, but they have a less sweet flavor. Unripe fruits will ripen best at room temperature. To consume the fruit, divide it into halves and scoop out the pulp with a spoon. The Purple Passion Fruit is also used to prepare salads, juices, sauces, ice cream, and custards. Its skin is not edible.
