A cake with a mix of chocolade and Sauerkraut. Makes you vomit? Most people eat the cake and like it and have the vomit feeling after learning about the recipe. Like eating a rat and learn after what it was. The recipes are old, was even in the cooking diary of my grandma while shevisited a cooking and householding school.

So why the recipe of this strange mix tastes so good? Sauerkraut and chocolade share some aromatic acids. So the Sauerkrauts boosts the chocolade taste. Molecular kitchen recently recovered the old recipes and explined why it works in german TV.
