How to make
Beat the butter and sugar until you get a fluffy cream. Add the egg yolks one at a time, and after whipping them, add the flour, starch and almonds.
Finally, mix with the egg whites that you've beaten into thick snow with a pinch of salt. Pour the mixture into a tray with baking paper and put the kuchen to bake in a low to moderate oven for an extended period.
Serve the baked kuchen with marmalade.
