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 body that make up the mash.
Hot milk or cream
Adds moisture and richness so the mash becomes smooth rather than dry.
Butter
Adds fat for flavour and a silkier mouthfeel.

The step that matters

Let the potatoes dry completely after draining. Excess surface water dilutes the mash and makes it gluey or loose. Letting steam escape keeps the texture thick and fluffy when the liquid is added.
