This is a "never-fail" recipe for the microwave.
Place the crushed pineapple, dried fruit, sherry, brown sugar, vanilla essence and butter in a casserole dish and cook on High for 6 minutes. Allow to stand until cool.
Fold in the flours, mixed spice, bicarbonate of soda and the lightly beaten eggs. Pour the mixture into a greased 24 cm ring dish*, and cook for 18 minutes on Medium. Cover with a tea towel and allow to stand for 20 minutes. Turn out onto a wire rack.
