Melt the butter in a saucepan, add the poppy seed filling, water, jam, sugar, spices and heat. Set it aside to cool. Add raisins, lemon peel and chopped nuts to the cooled mixture
Split the dough into two equal parts, then roll out the dough until it’s flat. Fill both with filling, and roll them up. Beat one egg and spread it over the poppy seed roll. You can also sprinkle it with almond flakes. Bake in a preheated oven for about 50 minutes at 320F.
