I really like desserts made from sour fruits like berries and passionfruit. Not everyone likes passionfruit because it is a bit strange. They're slimy and sour, and also "crunchy" at the same time, because of the seeds, which are edible. But the texture contrast is why I love this fruit on otherwise sweet desserts, like a pavlova or a soufflé.
