Combine pineapples, cherries, lemon and orange peels, light and dark raisins, cranberries, almonds, walnuts along with half a cup flour.
Add the fruit-nut mixture into the batter, mix with a wooden spatula to combine them well.
Turn the batter into the greased baking tin and smoothen the surface to even out.
Bake for about 1 hour till a skewer inserted in the center of the cake comes out clean.
Glaze, if preferred. Slice and serve.
