600gfruits of your choice + 15g all-purpose white flour
Combine the egg yolks with the brown sugar and mix until pale and light. Add the vanilla and lemon zest then stream in both fats.
Whip the egg whites until frothy, then start adding the white sugar gradually, mixing until stiff and shiny.
Using a spatula, fold in the egg yolk mixture then start adding the dry ingredients (flour, cornstarch, salt and baking powder - sifted together). Add the dry ingredients gradually, mixing with the spatula carefully and gently to prevent deflating the batter.
Level the batter in a 30x40cm baking tray.
Sprinkle on top the fruits mixed with 15g flour and top it all with almond slices.
Bake in the preheated oven at 160C for 35-40 minutes.
