Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the main body of the dish and carry the sauce.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded texture.
- Flour
- Thickens the cream and butter into a binding sauce that clings to the beans.
- Cream
- Adds moisture and richness, softening the sauce's texture.
- Onion or shallot
- Softens and adds a mild savory aroma to the sauce base.
The step that matters
Adding the flour, cream and butter. Flour should be stirred in thoroughly and butter added gradually so the sauce thickens smoothly without lumps or greasy separation.
Swap the onion
How well each one fits the dish's main ingredients (beans, parsley, lemon, butter, flour, cream, nutmeg):
- Shallotfits better
- Arrowrootfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against beans, parsley, lemon, butter, flour, cream, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
