Bring the milk, salt, vanilla sugar and durum wheat semolina to the boil, stirring vigorously, and continue to simmer for 5 minutes. Mix the butter with sugar until foamy, add the egg yolks, zest from one lemon and finally the semolina. Beat egg whites into snow and fold loosely into the semolina mass. Put 500 g of boiled cherries without juice in a greased casserole dish sprinkled with semolina. Pour the semolina over it and smooth it out. Bake the casserole in a preheated oven at 200 ° C for about 25 minutes.
Thicken the cherry juice with cornstarch and serve as a sauce.
