De-stem, wash and stone the cherries. Boil up the cherries, cinnamon stick, lemon peel, 100 g sugar and 1 litre water. Simmer for 3-4 minutes at low heat. Stir the starch in a little cold water until smooth and bind the cherries with it.
Season again with sugar to taste. Chill the cherry peel. Bring milk, fat, salt and 1 teaspoon of sugar to the boil. Sprinkle in semolina while stirring and continue stirring for 1 minute. Remove semolina from the stove.
Separate the egg. Stir the egg yolk into the semolina. Beat egg white until stiff, fold in. Bring slightly salted water to the boil. Use 2 teaspoons of the semolina mixture to cut off small dumplings. Add to the water and let it simmer at low heat for about 10 minutes.
Remove the cinnamon stick and lemon peel from the cold peel. Arrange the cherry cold dish with the semolina dumplings and serve decorated with lemon balm.
