Mix the jelly powder, 1/4 l water and apple juice in a pot. Let it swell for about 5 minutes. Stir in 3 tbsp. sugar and heat until all is dissolved (or follow package instructions)
Pour the liquid into a flat form and chill, preferably overnight, until the jelly can be turned over
Wash and clean the strawberries and, depending on size, cut them in half or quarters. Mix the strawberries and 1-2 tbsp. sugar and leave to stand briefly
Remove the jelly from the edge of the mould with a sharp knife. Hold the mould briefly in hot water and then turn over
Dice the jelly and arrange on dessert plates with the strawberries. If necessary, dust with a little icing sugar and decorate with lemon balm leaves. Whipped cream or crème fraîche tastes good with it
