Blend apple compote, blueberries with liquid (keep 1 tbsp. for garnishing), 100 g yoghurt, cinnamon, vanilla pulp and sugar in a mixer. Pour into glasses immediately. Carefully pour the rest of the yoghurt and the retained blueberries onto them.
Garnish as desired with lemon balm.
Tip: If you use frozen wild blueberries, take about 200 g of thawed blueberries and add some more liquid (fruit juice or milk).
