What to do with these?

Day 87 - Rote Johannisbeeren


I was going through the market one day and saw these next to a box of raspberries. Something I hadn't seen before, so I bought them. They are called Rote Johannisbeeren...do you know what they are? They have an addictive sour taste.

I looked it up, they are red currants. But now I don't know what to do with them. Do you bake a pie? What would you do with currants? Leave me some ideas please, because I'm at a loss, and I have a lot of them sitting in the fridge.
