Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Stirred in as a paste, it thickens the cooking liquid into a looser stew.
- Lamb
- Provides the meaty base and rich flavor of the stew as it simmers.
- Potatoes
- Soften during simmering and add starch that helps body the broth.
The step that matters
Adding the flour paste. Flour must be mixed smoothly into a thin paste with cold water before it goes into the hot liquid. Added dry or lumpy, it clumps and resists dispersing. Boiling afterward lets the starch swell and thicken the broth evenly.
