Separate the egg. Beat egg white until stiff. Mix egg yolk and 2 tablespoons of milk. Bring the remaining milk, 45 g sugar (3 tablespoons), vanillin sugar and lemon zest to the boil. Remove lemon peel, sprinkle semolina while stirring and cook over low heat for about 5 minutes.
Remove from heat, stir in egg yolk and finally fold in egg white. Spread the mixture into a greased, flat dish (approx. 20x20 cm) and let it cool down. In the meantime stir 4-5 tablespoons of cherry nectar and sauce powder until smooth. Boil up the rest of the juice and 30 g sugar. Stir in the sauce powder and boil again for about 1 minute. Stir in frozen berries, put them into a bowl and let them cool down. Loosen the pouring mixture from the rim, turn it over and cut it into approx. 16 5x5 cm squares. Heat the fat in a pan and fry the semolina slices in portions until golden brown. Mix the remaining sugar and cinnamon and sprinkle the slices with it.
