Make the sauce
In a bowl, combine the horseradish, lemon juice, vinegar, Worcestershire sauce, ketchup, Tabasco sauce, and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main seafood element, staying tender and briny when kept cold and stirred gently.
- Lemon juice
- Adds acidity that gives the sauce its sharp, bright flavour.
- Horseradish
- Adds pungent heat that sharpens the sauce's aroma and flavour.
- Ketchup
- Adds sweetness and body to the sauce.
- Worcestershire sauce
- Adds savoury depth and umami to the sauce.
The step that matters
Add the oysters last and stir gently. Oysters are delicate and cold; rough or prolonged stirring can break them apart and warm them, making the cocktail mushy and less fresh-tasting. Keeping them chilled and handling them gently preserves their texture.
Swap the lemon
How well each one fits the dish's main ingredients (oyster, horseradish, vinegar, sauce, ketchup):
- Limefits about as well
- Lemonthe original
- Avocadofits less well
- Applefits less well
Fit is the average pairing score against oyster, horseradish, vinegar, sauce, ketchup. Candidates are from the same food group and used in at least 100 recipes.
