Mix vinegar and Old Bay seasoning and use it as a dipping liquid for french fries. Also good for crabs and chicken, though it is definitely best on french fries.

The liquid is somewhat spicy, and if you drink it straight it tastes a little metallic and very spicy/acidic. I very strongly suggest that you don't drink it straight. This recipe seems to be a Maryland thing, since Old Bay is primarily known in Maryland. Specifically, it seems to be a popular choice in the many places that serve boardwalk fries in Ocean City, MD.
