Try this traditional recipe for German Mohnkuchen – that’s Poppy Seed Cake with Cherries and Crumble topping – a classic German cake with homemade poppyseed filling. Can be made with fresh or frozen cherries.
First, mix 300 g (2 1/2 cups) flour, 100 g (1/2 cup) sugar, and a pinch of salt in a bowl. Then cut the butter into small cubes and knead it into the flour mixture with your hands until you have nice streusel/crumble. Thoroughly grease a 26 cm (10-inch) springform pan and press two-thirds of the streusel mixture into the pan to form a base and a roughly 5 cm (2-inch) high edge. Place this prepared springform pan in the fridge while you work on the filling.
Bring 1 liter (4 cups) of milk to a boil in a large pot. Once it begins to simmer, add the rum, cinnamon, vanilla sugar or vanilla paste, and lemon zest. In a separate bowl, mix the ground poppy seeds, semolina, cornstarch, and sugar. Carefully stir this mixture into the boiling milk and let it simmer on low heat for about two minutes. I like to add a tablespoon of soft butter at this point. Then, transfer the mixture to a bowl and let it cool for five minutes.
