I just want to say that putting caviar on Pringle's is a terrible, terrible idea.
All you're going to taste is fishy salt.
@mcfate Well, to be fair, caviar and mashed potatoes go great together. How do I know? I ate a lot of them at a mashed potato station at a memorable wedding reception. I seemed to be the only one brave enough to try the combo, but I thought it REALLY worked. It was delicious, and I went back for more. I also enjoyed myself at the chocolate fountains (no caviar there, but some equally interesting combos).
