Orange Sponge Tube Cake
This is a favorite from a very old better homes and gardens book. I use it to make my orange icebox cake (recipe 75433).

Beat the egg yolks until very thick and light-colored.

In a separate bowl , beat the egg whites and cream of tartar until they reach the soft-peak stage.
Gradually add the remaining 1 / 2 cup of sugar.
