Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the main body of the dish and absorb flavour during long simmering.
- Butter
- Adds richness and fat that carries flavour and gives a smooth mouthfeel.
- Flour
- Rubbed into the butter, it thickens the cream and helps bind the sauce.
- Sweet cream
- Adds moisture and richness, combining with the flour to form a creamy sauce.
The step that matters
Stir in the butter, rubbed into the flour, and the sweet cream. Adding the flour-butter mixture to hot liquid without first blending it smooth can leave lumps. Rubbing the butter into the flour separates the flour particles so they disperse evenly before thickening.
Swap the beans
How well each one fits the dish's main ingredients (pepper, butter, flour, cream, pork):
- Almondfits better
- Chestnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against pepper, butter, flour, cream, pork. Candidates are from the same food group and used in at least 100 recipes.
