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

What each ingredient does

Flour
Thickens the cooking liquid into a smooth, thick sauce.
Butter
Adds richness and a smooth, glossy mouthfeel to the sauce.
Carrots
Provide the main body, sweetness and colour of the dish.
Green peas
Add bulk, mild sweetness and a bright green colour.

The step that matters

Simmer until thick. Flour thickens only when it is heated with liquid long enough for its starch to swell. Stopping early leaves a thin, floury sauce, while over-reducing can make it pasty.

Swap the peas

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

  1. Chickpeafits better
  2. Chestnutfits better
  3. Lentilsfits better
  4. Peasthe original

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