I'd freeze all you can't process.
For cake:
make sweet short crust, pre bake
stiffen 5 egg whites with 200 g sugar, gently add 100 g ground hazelnuts or almonds, add 500 g redcurrants or mixed red and black (yum), bake for 35 -40 minutes on 180C
Sauce for fish, like salmon or trout
bring a few handfuls of redcurrants with a few tablespoons of sugar (and salt to taste) to the boil, once soft, pass trough a sieve
