Did you know that the cashew nut we eat grows on the outside of a fruit? Every nut represents a fruit, perhaps explaining what cashews are so expensive. Native to Brazil, Ticos and other Spanish speakers call the fruit and nut marañón. People make a juice of the fruit and it's one fruit I just don't like. It smells bad to me. I'll stick to eating the delicious nuts.
Grenadilla is a fruit related to passion fruit. The outside has a crisp, papery layer. Inside the many small seeds are each inside a small packet of juicy fruit. I scoop the insides into a blender and run at top speed briefly. Next I use a sieve to remove the seed particles. The seeds are edible so a few bits of seeds getting through isn't a problem. Then I make a smoothy with some yogurt, sugar, and ice. It's very aromatic and quite similar to passion fruit.
