What each ingredient does

Oysters: Provide the main seafood element, served raw in the glass.
Catsup: Supplies sweetness, body and tomato flavor to the sauce.
Lemon juice: Adds acidity that brightens the sauce and balances the sweetness of the catsup.
Vinegar: Adds sharp acidity, making the sauce distinctly sour.
