Wash the lemon and rub dry. Peel off the peel in fine strips with a julienne sharpener. Squeeze lemon. Melt 3 tablespoons of sugar in a pan. Turn the almonds in it, put them on oiled aluminium foil and crush them roughly.
Wash, quarter and core the apples. Cut apples into slices. Melt 2 tablespoons of sugar again. Add the apple slices, add lemon juice and stew at low heat for about 3 minutes. Whip cream until stiff.
Cut the vanilla pod lengthwise, scrape out the vanilla pulp and stir into the cream with the remaining sugar. Arrange apple slices with stock and some cream on a dessert plate. Sprinkle with almond brittle.
Decorate with lemon balm leaves, lemon slices and strips.
