Havnt grown it myself but read that it tastes like a tart cucumber with a tinge of sweetness.
Oscar sells the seeds on fruitlovers so Im sure he could provide more info:)
It reminds me of what they call fruit salad fruit a related plant that I have grown but is perpetually plagued by pests especially aphids
This family of plants is very interesting I found out a short while ago that nightshade berries are edible and they even make what is supposed to be a delicious jam from it at one of my local markets(I have been abit chicken to try though!)
Mandrake amazingly also makes an edible fruit and that surprised the hell out of me!
