Start whipping with a mixer at high speed. The mass will gradually begin to lighten. The longer you whisk, the thicker the foam becomes. I whipped for 5 minutes. and this is the foam I got, quite dense. Next, this foam can be spread on a milkshake, using a teaspoon. But I decided to experiment and added a thickener for cream to the foam, beat it with a mixer at high speed and it turned out a thick mass, like cream.
