Add the sifted flour with baking powder. Mix gently. You can mix it with a mixer at low speed.
Put the dough in paper capsules for 2/3.
Bake for 15-20 minutes at 180 C.
For the cream, using a mixer, lightly beat the egg whites. Add sugar, vanilla and citric acid. Put it in a water bath so that the bottom does not touch the boiling water. Beat with a mixer for 6-9 minutes. The mass turns out to be snow-white, lush. When the cream begins to whisk on the corolla, remove from the water bath and whisk for another 3-4 minutes. Let the cream cool down.
