I have a question about step 3 on the recipe "Lemon Birthday Cake" from Eric Liftin. It says:
"Separate the eggs for the frosting. Dump 4 of the yolks in the main bowl; repurpose the rest as you like. Put aside the whites (in a stainless bowl). Whisk in the 8 eggs and beat until foamy. Whisk in the cream and rum."
Would you please clarify this step, how many yolks and how many whites go in which bowl, and together or separately?
