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

What each ingredient does

Potatoes
Provide the starch that gives the mash its body and fluffy texture.
Hot milk
Adds moisture and softness, loosening the mash so it stays smooth.
Butter
Adds fat for richness and a silkier mouthfeel.

The step that matters

Drain the water off. Excess water left in the pot dilutes the mash and makes it watery, so the potatoes should be drained thoroughly before mashing.
