  2. Add flour and brown slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Browned with the fat, it thickens the liquid into a light sauce.
Brown sugar
Adds sweetness and depth that balances the vinegar's sharpness.
Vinegar
Provides the sour note that defines the dish.
Canned string beans
The main vegetable, simmered until they absorb the sauce.

The step that matters

Browning the flour. Flour cooked in fat must be stirred and browned only slightly; if it scorches, it turns bitter and dark, and the sauce loses its clean flavor. Stirring keeps it even.

Swap the peach

The recipe marks peach as optional. How well each one fits the dish's main ingredients (beans, flour, sugar, cinnamon, vinegar):

  1. Raisinfits better
  2. Vanillafits better
  3. Blueberryfits better
  4. Peachthe original

Fit is the average pairing score against beans, flour, sugar, cinnamon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
