Drain the apricots well on a sieve. Mix 25 g sugar and apricot liqueur. Add the drained apricots. Leave to stand for about 10 minutes. In the meantime, separate the eggs. Place the egg yolks, salt, 50 g sugar and baking oil in a bowl and whisk until creamy white.
Stir in cream and flour. Then beat the egg whites until stiff, add the remaining sugar. Fold the beaten egg white into the egg yolk-flour mixture in portions. Pour the mixture into four ovenproof greased moulds.
Spread the apricots evenly in the middle of the dough. Bake in the preheated oven (electric: 175 °C/ gas: level 2) for 25-30 minutes. Remove from the oven, dust with icing sugar and decorate with lemon balm as desired.
