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

What each ingredient does

Potatoes
Provide the starch and bulk that form the body of the mash.
Butter
Adds fat for richness and a smoother, silkier mouthfeel.
Hot milk or cream
Adds moisture so the mash turns creamy rather than stiff.

The step that matters

Drain and dry the potatoes completely. Surface water dilutes the mash and makes it gluey or loose. Letting the potatoes steam dry lets the liquid evaporate so the liquid you add is absorbed and the texture stays fluffy.
