What to do with egg yolks?
I made an angel food cake a few weeks ago and make pound like sponge cakes in a couple of loaf pans with the yolks. Then me being someone who likes to play, I took one of the sponge cakes,cut it into slices,then cut the slices to resemble French fries,brushed them with butter and put them in the oven on a cookie sheet to toast and brown. Sprinkled them with sugar, lined a fry basket with a paper towel , put the "fries" in the basket with a small bowl of ketchup (red tinted confectioner's sugar icing a little on the thin side). Then served it to my niece's kids who didn't quite know what to make of them but I thought it was a cute idea.
i'm sure there are plenty of non-Hollandaise and non-dairy ideas here:
I had this issue when I made an angel food cake. I found a lemon curd recipe that uses 8 yolks. It tastes great (but no better than my usual recipe). It's on epicurious: http://www.epicurious.com/recipes/foo...
If you don't have 8 yolks, you could probably divide the recipe in half (or whatever).
Note: I didn't make the cake, so I can't tell you if it's any good (although you obviously wouldn't be trying it now anyway).
