I would like to point out that this amount of ingredients is for 2 rolls! If you want to make 1 roll, then the number of ingredients should be halved. But I think you don't have to do that, because the pastry is so tender and delicious that your family and friends will surely like it. Separate the whites from the yolks. Beat the whites, gradually adding the sugar (1/2 cup). Then whip until stiff peaks.
