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, boiled long until very tender.
Flour
Starch swells in hot liquid, thickening the cream into a sauce.
Butter
Adds richness and a smooth, glossy mouthfeel to the sauce.
Sweet cream
Provides fat and body, forming the creamy base of the sauce.

The step that matters

Stirring in the butter and flour mixture. Flour thickens only as its starch swells in hot liquid. Stir the butter-flour mixture into the cream thoroughly so it disperses evenly and does not form lumps.

Swap the beans

How well each one fits the dish's main ingredients (pepper, butter, flour, cream, pork):

  1. Almondfits better
  2. Chestnutfits about as well
  3. Pistachiofits about as well
  4. 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.
