Separate the whites from the yolks. Place the whites in one bowl and the yolks in another. Mix the soft butter, sugar and vanilla sugar in a bowl.
Add flour, yolks and mix until smooth.
Roll the dough into a sausage, wrap it in cling film and put it in the refrigerator for 30 minutes.
Cut the sausage into circles. Sprinkle with flour and roll out a little.
Place the resulting circles into basket molds, forming the bottom and sides, and place in the freezer for 5-10 minutes.
Take the molds out of the freezer and place them in a preheated oven. Bake for 10 minutes at 180⁰С.
Meanwhile, prepare the protein cream. Beat the egg whites with a mixer for 1-2 minutes. Add the powdered sugar, continuing to beat. Beat for another 10 minutes. Add the citric acid, beat for a couple more minutes. Finally, add the starch and beat for another 1 minute.
Take the finished baskets out of the oven. Then put raspberry jam inside the baskets and whipped egg whites on top.
Bake the baskets with cream for 40-50 minutes in the oven at 140⁰С. The meringue should be slightly creamy. Cool the dessert before serving.
