Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender and flavorful as it heats in the broth.
- Flour
- Thickens the broth into a smoother, heavier soup body when cooked with butter.
- Butter
- Adds richness and helps the flour blend smoothly into the liquid as a thickener.
- Gravy or broth
- Forms the liquid base that carries the flavor of the whole soup.
The step that matters
Thickening with flour and butter. Flour must be cooked into the butter and hot liquid so it dissolves evenly; added raw or in lumps it stays grainy and the soup turns thick in patches.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, butter, mutton):
