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

What each ingredient does

Crab meat
Provides the main savoury flavour and substance of the filling.
Butter
Adds richness and carries flavour through the filling.
Flour
Thickens the cream and celery mixture as it cooks.
Cream
Adds moisture and body that thickens into a spreadable filling.
Celery
Adds crisp texture and a mild vegetal flavour to the filling.

The step that matters

Simmer until the moisture is mostly evaporated. Cooking off excess liquid keeps the filling thick enough to stay on the toast instead of soaking it and making it soggy.

Swap the celery

How well each one fits the dish's main ingredients (butter, crab, meat, flour, cream, pepper, sherry):

  1. Nutmegfits better
  2. Parsleyfits about as well
  3. Thymefits about as well
  4. Celerythe original

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