Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brisket of beef
- Provides the main meat, which becomes tender through long simmering.
- French beans
- Form the bulk of the dish and soften as they stew.
- Flour
- Thickens the cooking liquid into a light sauce.
- Vinegar
- Adds acidity that balances the sweetness and richness of the dish.
- Brown sugar
- Adds sweetness and depth that offsets the sharpness of the vinegar.
The step that matters
Stirring in the flour, sugar and vinegar mixture. Flour mixed directly into hot liquid can clump. Combining it first with the sugar and vinegar, then stirring it evenly into the beans, helps it thicken smoothly.
Swap the onion
How well each one fits the dish's main ingredients (beef, beans, pepper, flour, sugar, vinegar):
- Capsicumfits better
