Bring the milk, 25 g sugar, vanillin sugar, lemon peel, rice and salt to the boil and allow to swell over a low heat for about 30 minutes. In the meantime, drain the cherries on a sieve and collect the juice.
Pour the apricots onto a sieve, collect the juice as well and cut the apricots into slices. Mix the cherry and apricot juice. Stir cornflour and 5 tablespoons of juice until smooth, bring the remaining juice and 30 g sugar to the boil, stir in cornflour and bring to the boil again briefly.
Fold in the fruit. Beat egg whites, lemon juice and remaining sugar until stiff. Divide the compote and rice into 4 ovenproof portion bowls, add the beaten egg white and sprinkle with almonds. Bake in the preheated oven (electric: 200°C/ gas: level 3) for 15-20 minutes.
Decorate as desired with lemon balm.
