Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef brisket
- Provides the main meat and rich flavor as it simmers into tender pieces.
- French beans
- Add body and bulk to the stew while absorbing the cooking liquid's flavor.
- Flour
- Thickens the cooking liquid into a slightly glossy, smoother sauce.
- Vinegar
- Adds acidity that brightens the stew and balances the sweetness and richness.
- Brown sugar
- Adds sweetness and a subtle caramel depth that rounds out the sourness of the vinegar.
The step that matters
Adding the flour, sugar, and vinegar mixture. Flour clumps if added directly to hot liquid. Mixing it first into a smooth blend and stirring it in evenly keeps the sauce smooth and thickened rather than lumpy.
