Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green beans
- Form the main body of the salad, providing the vegetable base for the dressing.
- Lard
- Provides fat for the roux and carries flavor into the dressing.
- All-purpose flour
- Thickens the dressing with the melted lard into a smooth, cohesive sauce.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavor.
- Cream
- Adds richness and softens the sharpness of the vinegar in the dressing.
The step that matters
Let the mixture boil for a few minutes. Flour must cook in hot fat and liquid to thicken fully and lose its raw starchy taste. Boiling also activates the starch so the dressing becomes smooth rather than pasty.
Swap the green beans
How well each one fits the dish's main ingredients (pepper, flour, onion, vinegar, cream):
- Mustardfits better
- Horseradishfits better
- Chivefits better
- Green beansthe original
Fit is the average pairing score against pepper, flour, onion, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
