What each ingredient does

Tomato catsup: Provides the sweet, tangy base flavor of the cocktail sauce.
Lemon juice: Adds acidity that brightens the sauce and balances the sweetness of the catsup.
Oysters: The main ingredient; served raw, they are the centerpiece of the cocktail.
Boston brown bread: Serves as a soft, slightly sweet base for the oysters alongside the sauce.
