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

What each ingredient does

Potatoes
Their starch thickens the soup and gives it a smooth, body-rich texture once mashed.
Milk
Adds moisture and loosens the mashed potato into a pourable soup.
Butter
Adds fat for richness and a smoother mouthfeel.
Celery
Adds a mild, savoury aroma and background flavour as it cooks with the potatoes.

Swap the celery

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

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