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

What each ingredient does

Potatoes
Their starch breaks down during long boiling, thickening the water into a body-rich soup.
Butter
Adds fat that gives the soup a rounder, richer flavour and smoother mouthfeel.
Cream
Adds fat that makes the soup creamy and softens its texture.

The step that matters

Boiling the potatoes for 2 hours. Potatoes that boil long enough soften and release starch, which thickens the liquid. Stopping too early leaves the soup thin and the pieces firm, while overcooking can make it pasty or cloudy.
