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, which softens and becomes tender as it boils.
Baking soda
Raises the water's alkalinity, which helps the beans soften faster and keep a bright green colour.
Heavy cream
Adds fat and richness, giving the beans a creamy coating.
All-purpose flour
Thickens the cream with the butter, giving a smoother, heavier sauce.

The step that matters

Cooking the beans in baking soda water. Baking soda softens the beans quickly, so they can turn mushy or lose shape if boiled too long. Test for tenderness often and drain as soon as they are done.

Swap the beans

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

  1. Almondfits better
  2. Pistachiofits better
  3. Chestnutfits better
  4. Beansthe original

Fit is the average pairing score against butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
