[Question] Recipes for 12 egg YOLKS?

Following up on the "Baking in the American South" post, I picked up some Nordic Ware pans today for bundt cakes and pound cakes.

Included was a Angel Food cake recipe requiring 12 egg WHITES.

I have no problem separating, but it seems a waste of a DOZEN egg yolks.

Any ideas on what to put them in?

I guess I could make the egg sauce bottle here, but I'd have to buy a Sou Vide machine. :(
