Passion fruit (aka granadilla, gulpa) is a roughly plum-sized & slightly egg-shaped fruit with a thick, inedible outer rind. Once cut in half, strange but delicious yellow-orange jelly is revealed inside, dotted with small edible black seeds.
Fresh passion fruit is highly prized by chefs (particularly pastry chefs) because of its rich, incredibly complex tart-sweet flavor. Not only is it delicious in sauces, desserts, and beverages, but it is also quite potent, so you don’t have to use as much as many other fruit varieties. It is high in vitamins C, B5 and B2.
These are purple passion fruits, a variety commonly found in Australia & New Zealand. They’re smaller than yellow passion fruit, but are the variety preferred by chefs because they're richer, less acidic, and juicier.
