Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton shoulder
- Provides the main meat, which becomes tender through long boiling.
- Celery
- Softens in gravy and forms the body and flavor of the sauce.
- Flour
- Thickens the celery sauce so it coats the meat.
- Butter
- Adds richness and smoothness to the thickened sauce.
- Gravy
- Cooks the celery and carries its flavor into the sauce.
The step that matters
Thicken the celery with flour and butter. Flour needs to be cooked into the liquid to avoid a raw, starchy taste and lumps. Adding it to a simmering sauce and stirring keeps it smooth and lets it thicken evenly.
Swap the celery
How well each one fits the dish's main ingredients (mutton, flour, butter):
- Capersfits better
- Turmericfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against mutton, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
