This original sponge roll with the bright mandarin filling will decorate any festive table. Juicy tropical notes combined with delicate buttercream give the dessert a wonderful taste that will appeal to both young and adult sweet lovers.
We prepare products for the biscuit roll. The cream must be pre-cooled in the refrigerator.
To prepare the biscuit dough, first separate the yolks from the whites.
Beat the whites with 3 tablespoons of sugar and a small pinch of salt until firm, dense foam.
Beat the yolks with 1 tablespoon of sugar until a dense white mass.
On a medium grater, rub 1 teaspoon of lemon zest.
Combine proteins, yolks, flour and lemon zest.
Mix everything well with a spoon or at low speed of the mixer.
Cover the baking sheet with parchment, then grease with butter and a thin layer (no more than 1 cm), pour out the biscuit dough.
We bake the biscuit cake in an oven preheated to 170 degrees for about 15 minutes.
While the crust for the biscuit roll is baking, you can do the cream. To do this, add condensed milk and 2 tablespoons of sugar to the chilled cream. Then beat until creamy.
Apply butter cream on the cooled cake. A little cream can be left to decorate the roll. Having retreated from the edge about 5-7 cm, we spread the tangerines closely. I got a narrow cake on which 5 tangerines fit, so I disassembled the extra tangerine into slices and decorated the top of the roll.
Gently (so as not to squeeze out the cream) roll up the roll with the tangerines. Cut off the excess edge with a sharp knife.
It is advisable to leave the finished roll in the refrigerator for several hours – then the cream will harden even more and it will be easier to cut the roll into pieces with a sharp knife.
Top the biscuit roll can be sprinkled with powdered sugar or cinnamon and garnished with cream. Sponge roll with tangerines is ready.
