First, beat the eggs and sugar until foamy. Then add the flour. Put granulated sugar on a baking paper so that the roulade does not stick to the top.
Then spread the mixture on the baking paper. Put the baking sheet into a preheated (to 200 °C) oven and bake for about 10 minutes.
When the roulade is golden brown, remove it from the oven. Spread the jam in the middle.
Roll up the roulade and sprinkle with sugar.
