Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- The main vegetable, cooked until tender while keeping its bright green color.
- Broth
- Adds moisture and savory flavor as the beans finish cooking.
- Cream
- Adds richness and body to the finished sauce.
- Butter
- Adds fat and flavor, giving the sauce a smooth, rich finish.
- Flour
- Thickens the cream and broth into a lightly bound sauce.
The step that matters
Serve immediately to preserve their green color.. Green vegetables lose their bright color when held too long after cooking, so serving promptly keeps the beans looking fresh.
Swap the beans
How well each one fits the dish's main ingredients (cream, butter, flour):
- Almondfits better
- Pistachiofits better
- Macadamia nutfits better
- Beansthe original
Fit is the average pairing score against cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
