Drain the cherries and collect the juice. Mix starch and 4 tablespoons of juice. Boil up the rest of the juice and vanilla sugar. Stir in starch and simmer for about 1 minute. Add the cherries. Leave to cool.
Melt 80 g butter and let it cool down. Put flour, lemon peel and 1 pinch of salt in a bowl. Mix milk, eggs and the liquid butter one after the other into the flour and stir everything into a liquid dough.
Leave to soak for about 15 minutes.
Grease 8 soufflé tins or ovenproof cups (approx. 200 ml capacity each) well and fill them to approx. 3⁄4 with the dough. Bake in the preheated oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3) for approx. 40 minutes.
(So that the soufflés do not collapse, do not open the oven door in between).
If necessary, loosen the edge of the pike from the moulds with a sharp knife and turn over. Dust with icing sugar and arrange with the cherries.
