1 lb plums (stoned and chopped)
2 oz ground almonds
6 oz butter
6 oz caster sugar
3 eggs
6 oz self raising flour
zest and juice of a lemon

Put all of the ingredients except the plums into the magimix and process for 2 mintues.  Put 1/2 the mixture into a well greased spring form pan, top with 1/2 the plums.  Repeat with the other half of the mixture and the other half of the plums.  Bake at 180 for 45 minutes.  It is not a beauty, but it tastes nice.
