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.
