Beat the egg whites with the water until stiff. Let the sugar trickle in while continuing to beat and mix well. Add the egg yolks and stir in. Mix the flour, baking powder and nuts and then carefully fold in.
Place the dough on a baking sheet lined with baking paper and smooth it out.
Bake in the preheated oven at 180 degrees for about 10-15 minutes.
Then turn it out onto a sugar-sprinkled kitchen towel and peel off the baking paper.
Spread evenly with the jelly and roll up tightly. Let cool down.
