Japanese Cotton Cake
1.
Boil the butter, sift into the low powder, and mix well
2.
Add condensed milk, mix well, add C and mix well again to make egg yolk paste
3.
Add sugar and a little salt to the egg whites, and beat until hard foaming (I only beat it to wetness, the tissue is not so delicate, it is best to beat it to hard)
4.
Mix the egg white paste and egg yolk paste in 3 times, pour it into the small mold, shake it to eliminate the internal bubbles, and bake in the oven
5.
Preheat the oven at 170 degrees and bake for 25 minutes
