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

What each ingredient does

Potatoes
Provide the starchy base that mashes into the dish's body and fluffy texture.
Milk
Adds moisture and creaminess, loosening the mash and softening its texture.
Butter
Adds fat for richness and a smoother, silkier mouthfeel.

The step that matters

Adding the boiling milk and butter. Hot liquid is absorbed more evenly into warm, mashed starch, giving a smooth texture. Cold milk cools the potatoes and can make the mash gluey or stiff.
