How to make
Separate the yolks from the whites. Mix the melted butter, powdered sugar, egg yolks, grated rind of 1 lemon and the cottage cheese. Beat the whites very well and add them to the mixture.
Add the flour and baking powder and mix well. If the mixture is too thick, dilute it with a little lemon juice. Bake at 360°F (180 °C) until tender.
If you want a more pronounced lemon flavor, add a few drops of lemon juice. Note that this cake does not rise, but has a very nice lemon-butter flavor.
