They go really well as a sauce (like apple sauce) with rich meats such as… goose! And the French call them groseilles à maquereaux because they like them with mackerel.
I can't improve on the excellent suggestions already made. I love gooseberries, but sadly my little bushes didn't produce much this year after a hard pruning last year.
Just finished top and tailing 1/2 a bucket of gooseberries from the allotment. Tedious job, but worth it when you can get them from the freezer all winter, My favourite is gooseberry pie, possibly with a puff pastry top.
