Drain the peaches and collect the juice. Cut 1 peach half into slices and put aside. Soak gelatine in cold water. Mix tea drink and peach juice well. Stir yoghurt, lemon juice and sugar until smooth. Stir in the juice mixture
Squeeze out the gelatine and dissolve over a mild heat. Mix with 5 tablespoons of yoghurt mass, then stir into the rest. Cool until the mass begins to gel
Whip the cream until stiff and allow the vanillin sugar to trickle in. Dice half of the peaches, puree the rest
First add peach cubes, then cream in portions to the yoghurt mass. Alternately layer with puree in dessert glasses or a bowl. Leave to cool for at least 4 hours. Garnish with peach wedges and possibly lemon balm
