Separate the egg whites from the yolks and add 3 pieces of yolks and 10g of sugar and whisk until it turns ivory.

Mix 3 egg whites slightly with a whisk and when it starts to bubble, add 35g of sugar and make 100% meringue

Add beaten egg yolk to a firm meringue and mix evenly as if cutting with a knife.

Mix the soft flour and baking powder on a sieve with the egg mixture
Mix the dough gently as if cutting it with a knife so that it doesn't break off.

Place the finished dough in a piping bag.

Place parchment paper in a pan, squeeze the dough diagonally, and sprinkle sugar powder evenly over the dough.

I baked it in a preheated oven for about 170-15 minutes

The baked biscuits were picked up with parchment and moved to a cooling net to cool them down

Mix with whipped cream and sugar, whip firmly, and prepare strawberries by washing them clean.

Apply whipped cream evenly to the inside of the biscuit from which parchment paper was removed, place strawberries on top, and roll it to complete the roll cake.
