The maracuja has a family member that is much more familiar: the passion fruit. The granadilla is also part of the same family. The maracuja can be recognised thanks to its yellow-green skin and oval shape. When sliced open, the similarity with the other two family members is obvious. Inside the maracuja you will find yellow-orange pulp, full of small edible seeds. But, contrary to many other fruits, don't discard the seeds as they are the real treat here.
If passion fruit is too sweet for your liking, maracuja is a tasty alternative. Still sweet, but with a little more tang. The skin indicates how ripe the fruit is. The fruit tastes at its best when the skin is wrinkled. Preferably buy the maracuja while the skin feels firm and is not too wrinkled. Do not wait too long before eating as the fruit dries out quickly.
