For the dough:
300 g of flour
100 g of sour cream (a thicker, tangier Eastern European-style variety)
2 eggs
50 g of butter (or margarine)
1 tablespoon of sugar
a pinch of baking soda
For the filling:
2 lemons
200 g of sugar
100 g of nuts (walnuts or almonds work well)
100 g of raisins
1 egg white
powdered sugar
vanillin
Prepare the dough: Cut the butter into the sifted flour mixed with baking soda. Add the sugar, egg yolks, and sour cream, then knead until the dough is crumbly. Place the dough in a cool spot overnight or for 2 hours.
Roll the dough out into a thin circle, stretch it by hand, brush it with egg white, add the filling, and roll it up. Cut the roll into two pieces and place them on a greased baking sheet. Brush with egg white, sprinkle with vanilla sugar, and bake in a preheated oven at 220°C (about 425°F) for 30 minutes. Once baked, cut the roll into pieces and dust with powdered sugar.
To prepare the filling:
Pour hot water over the lemons 2–3 times, draining each time. Then boil the lemons, drain the water, and let the lemons cool. Cut the lemons in half, remove the seeds, and grate the fruit together with the peel on a coarse grater. Mix the grated lemons with sugar and cook until translucent. Chop the nuts finely, add the washed raisins, and combine them with the lemon mixture.
