preparation
Beat together egg yolk, honey, water and sugar for 10 minutes, before combining with flour, poppy seeds, baking powder, vanilla sugar and cinnamon. Beat egg whites with a pinch of salt and two dessertspoons of sugar until they form peaks and carefully fold into dough mixture. Spread out roulade mixture to a finger’s thickness on a baking tray covered with greaseproof paper and bake for 10 minutes at 180° C. Transfer onto some kitchen towel, roll out slightly and allow to cool. Whip cream and fold in jam. Cover sponge with mixture and roll up tightly again. Finally, dust with icing sugar and serve.
