Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main raw seafood base, served cold in their shells or glasses.
- Tomato ketchup
- Adds sweetness and body to the sauce, balancing the sharp seasonings.
- Lemon juice
- Adds acidity that brightens the sauce and cuts the richness of the oysters.
- Horseradish
- Contributes sharp pungency and aroma to the sauce.
- Worcestershire sauce
- Adds savoury depth and umami to the sauce.
The step that matters
Chill the sauce mixture. Cold sauce keeps the oysters cold and firm when served, since warm sauce would begin to cook their edges and dull their fresh flavour. Chilling also lets the horseradish and seasonings blend smoothly.
