Separate the egg yolk protein and add 1 scoop of sugar to the egg yolk.
The protein is added with sugar to make it into a hard cream. This step is the most difficult to do. Po main does not have a professional hair dryer, had to use a small power mixer, the cream did not hit hard, so a pity...
Sift the flour into the egg yolk solution. It is best to buy a professional sieve. The flour thus sifted out is fine enough to not agglomerate.
Add the cream that the protein is sent and mix well.
Pour the cake paste into a tin foil. Or a microwave-heatable container is fine.
It takes 7-8 minutes for the high fire to come out. Po The first time I cooked for 10 minutes, it was a bit hard, and I will try again next time.
