What sauce would make the best beverage? (Extra points if you can come up with an answer for both a savory and a sweet sauce).

I'm leaning toward apple sauce. It's already something that's eaten on its own. In terms of a savory sauce, if dressings count—I think they do—then greek dressing would be my answer. Dressings in general tend to be more drinkable than typical condiments. Anyways, what's your opinion?
