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 flavour and tender texture as the centrepiece of the cocktail.
Tomato ketchup: Supplies sweetness, body and the base colour and flavour of the sauce.
Tarragon vinegar: Adds acidity and a sharp, herbal bite that cuts through the sweetness of the ketchup.
Worcestershire sauce: Adds savoury depth and umami to the sauce.
Celery: Adds a fresh, crisp, slightly vegetal note on top of the cocktail.
