here's the recipe:
3 eggs
1 dl sugar
2 dl white flour
1 tea spoon of baking powder
(some vanilla if you like, but it's not a must. i use 1 spoonful of vanilla sugar)
½dl milk or low fat cream
whip eggs and sugar. mix the baking powder to the flour and add to the egg-sugar foam. mix well and then add the milk/cream.
place baking paper on oven tray and fold from corners (about 30cmx40cm) spread the dough on paper and bake in 250○C for a couple of minutes until it get a little colour
then place a piece of baking paper on the table (bigger than the cake lol) and whip some sugar on it. take the cake from the oven and turn it on the sugar coated paper so that the top side comes under. remove the paper that was under the cake in the oven
spread jam on the cake (you can also add whipped cream or cream cheese (like philadelphia) or butter cream or mashed fruits or berries). leave about 4 cm from the other side clean. roll the cake using the paper under it. make as tight as you can. put to the refrigerator for a while.
