Separate the whites from the yolks. The whisk and the bowl in which you whip the whites, previously placed in the refrigerator. Whites beat until stable peaks. Suggest completely a win-win: starting, beat egg whites, add about 1/2H. L. alcohol. Yolks to pound until white, adding 3st. L. Very hot water. It's another secret in which the cake turns out tender and not dry. Gradually add in the egg yolks sah. powder and vanilla sugar. In yolk-sugar mixture gradually, stirring clockwise and from the bottom up, add the beaten egg whites. Then I carefully, in a few receptions add flour, mixing from the bottom up. The mass of sponge I have divided into 7 equal parts. Added colored food coloring to each portion and placed in different disposable cooking bags. You can take a file to cut the area wide CM1,5 approximately. On the tray lay a parchment. And now the fun part-lay out the dough strips candy bag, one color right next to another. Even if you have no hand dyes, but only the cocoa can divide the dough into two parts. But there's a caveat. Cocoa replaces the flour. So how much you put tablespoons of cocoa, so cups of flour should be less, and the dough will become stiff and tight. "Knitting," I was an accident. Strips of the pastry bag does not go perfectly smoothly, and bake the loaf must still equal thickness. I took a toothpick. Held across the strips, leveling the dough. I liked the effect. Therefore, the next stripe with a toothpick I held back. That turned out-take a toothpick to the right->->->->->, then left<-<-<-<-<-. And so to the end of the pan

Place the baking tray with the beauty in the oven cold. Now to set the temperature. 160* 25-30min. Watch for readiness. But time in vain do not lose. Dampen a clean kitchen towel, wring and lay on the table. Next, immediately prepare jam or any cream. Then preparation time will not be))). The finished seam will lay on a damp towel. Now the parchment is on top. Quickly, but carefully remove the parchment and roll the meat together with the towel for a minute ( personally I keep a rolled-up roll 30 seconds). Expand the cake. The dough from the wet towels will be pliable. Just throw in the towel. Quickly spread a layer of jam and re-roll the meat

If desired, the finished roll sprinkle with powdered sugar. Bon appetit!
