Cut 4 strips (each approx. 10 x 35 cm) from the paper. Place one strip around each soufflé dish (150 ml capacity; approx. 9 cm Ø) so that it is approx. 5 cm above the edge of the dish. Glue or bind
Drain the peaches. Puree finely except for 2 halves. Season to taste with cinnamon, vanilla sugar and lemon juice
Separate eggs. Beat egg whites until stiff. Let sugar trickle in. Add egg yolk and fold in. Whip cream until stiff. Fold egg mass first, then cream into the peach puree. Fill into the moulds and freeze for at least 4 hours
Remove paper. Smooth the parfait edge with a knife if necessary. Halve the remaining peaches and cut them into fans. Decorate parfait with remaining peaches, pistachios and possibly with lemon balm
You can easily prepare the parfait 2-3 weeks in advance and freeze it in foil
