You could always make a gooseberry fool, which is a traditional English recipe. Since they are already cooked, just drain them well and fold into some soft whipped cream. Put into bowls and chill about an hour.You can also crumble in some meringues or amaretti, to give a bit of crunch.
You can also warm them up, syrup and all, and serve them as a stewed fruit, over cake, or topped with some cream or custard.
I once had a sauce made with Gooseberry, butterm wine, and dill served over a peice of salmon, it was really good. I don't have an exact recipe but you can probably play around with it and get something pretty yummy.
Where did you get the can of gooseberries? Ever since I had that suace I've been trying to find them.
