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

What each ingredient does

Green peas
Form the main body of the stew and give it its bulk and flavour.
Lettuce
Softens as it stews, adding moisture and a mild vegetal sweetness to the broth.
Onion
Releases sugars and aromatic compounds as it cooks slowly, adding savoury depth.
Butter
Adds fat and richness, carrying flavour and giving the stew a smoother mouthfeel.
Egg
If stirred in, it can thicken the stew slightly as its proteins set with heat.
Flour
If added, it thickens the liquid by absorbing water when heated.

The step that matters

Adding the egg before serving. Egg proteins set when heated, so stirring it into a very hot stew can scramble it into lumps. Beating it first and stirring it in gently off the heat helps it blend smoothly and thicken the liquid evenly.

Swap the onion

How well each one fits the dish's main ingredients (peas, lettuce, butter, pepper, egg, flour, sugar):

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