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

What each ingredient does

Butter
Adds richness and body, and carries flavor through the stewed vegetables.
Old peas
Pulped and mixed into the gravy, they thicken the soup and give it body.
Beef gravy
Forms the savory liquid base that the pulped peas and vegetables are combined into.
Cucumbers
Stewed gently in their own liquid, they contribute moisture and a mild, fresh flavor.

The step that matters

Stew gently for 1 hour in their own liquid. Gentle heat lets the vegetables soften and release their flavor without boiling hard, which can break down color and texture. Keeping the stew gentle keeps the soup fresh-tasting and smooth.

Fit is the average pairing score against cucumber, lettuce, mint, onion, parsley, peas, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
