I gotta give it to mulberries, don’t get enough attention!
The buds of the flower Bauhinia variegata are both cooked amd used for pickles, spectacular stuff.
Wild strawberries (Fragaria vesca). Incredibly fragrant and sweet. Regular strawberryies can’t compare.
feijoa, a South American fruit that made it to New Zealand - now just about every backyard in NZ has one, or many of them
Wild blueberries. They’re smaller, sweeter, and grow on a low bush. The bigger, high bush blueberries may as well be a different fruit.
Water apples, or wax apple. Their name is pretty much self-explanatory in terms of the taste. Really refreshing in the tropics.
