The description I finally found for my cooking – open fridge and you whatever is almost rotten, was pushed to my limit here. Taste moldy blueberry = yuk. Just about throw out. Decide sugar masks everything but do pick out the worst of the rotting berries
Whisk 1/2 cup butter with a cup sugar and some vanilla until creamy
Add 4 eggs one at a time
Sift together a cup each almond and plain flour with 2 teaspoons baking powder
Add to mix in several portions alternating with a cup of buttermilk
Dump in about 3 cups blueberries
Pour into greased pan and bake at 150C until set about 30mins
Flip out and serve to delight of super yacht crew, once eaten tell them it was the moldy fruit they wanted to throw away, keep that you had second thoughts about it to yourself.
