How to cook
Put the pineapple slices to drain well from the liquid. In a bowl, mix the flour, starch, baking powder, salt. Separately, beat the butter with the sugar to a fluffy cream, add the eggs 1 by 1 and pour in the milk/juice and rum essence.
While stirring nonstop, add the dry ingredients to the liquid ones. Finally, stir with the lemon zest and raisins. Pour the mixture into a greased and lightly floured cake form, then arrange the pineapple slices which you've rolled in flour or breadcrumbs on top.
Put a few small bits of butter on top of the fruits and put it to bake in a preheated 347°F (175 °C) oven. Bake in the lower half of the oven until the cake rises well. If desired, sprinkle the baked Cake with Pineapple with a little powdered sugar while it's still warm.
