Huge Mess!

This is the third time I've tried to post this. I'm tempted to give it up because it isn't earthshaking. But I have a pound cake recipe that calls for whipping four egg whites with 1/4 t cream of tartar and then folding it into the batter. It makes it light. And it stays nice in the following days. But I make a huge mess when I make that cake. It's worth it, but there's a lot of clean up.
