Well, they are relayed to potatoes, so no wonder
Somewhere I have seen recipes for it, especially for jam, and I'm sure that would be delicious (mixed with some lemon juice etc for acidity)... But, mine never stayed so long, they were eaten straight away. I would rate them as good as blackcurrants, but, I have been eating currants all my life, and they're nothing special here, so, new varieties are welcome.
