Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tripe: Forms the main body of the dish and becomes tender with gentle simmering.
Butter: Adds richness and fat that carries flavour and gives the sauce a smooth mouthfeel.
Flour: Thickens the cooking liquid into a light sauce around the tripe.

Swap the parsley

The recipe marks parsley as optional. How well each one fits the dish's main ingredients (milk, butter, flour, pepper, oyster):

Nutmegfits about as well
Parsleythe original
Cinnamonfits about as well
Thymefits less well

Fit is the average pairing score against milk, butter, flour, pepper, oyster. Candidates are from the same food group and used in at least 100 recipes.
