Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw oysters
- Form the base of the cocktail and provide its main texture and briny flavour.
- Tomato ketchup
- Adds sweetness and body to the sauce that coats the oysters.
- Horseradish
- Adds sharp heat and aroma that cut through the richness of the oysters.
- Lemon juice
- Adds acidity that brightens the flavour of the oysters and sauce.
The step that matters
Serve very cold. Oysters must stay cold from shucking to serving, since low temperatures slow bacterial growth and keep the flesh firm and fresh-tasting. Serving them warm makes them soft and spoils their flavour quickly.
Swap the lemon
How well each one fits the dish's main ingredients (oyster, pepper, tomato, ketchup, sauce, horseradish):
- Limefits about as well
- Lemonthe original
- Avocadofits about as well
- Cherryfits less well
Fit is the average pairing score against oyster, pepper, tomato, ketchup, sauce, horseradish. Candidates are from the same food group and used in at least 100 recipes.
