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.
- Milk
- Adds moisture and softness so the mash becomes smooth and spreadable.
- Butter
- Adds fat for richness and a silky mouthfeel.
The step that matters
Stir over low heat until well combined. Overworking starchy potatoes after they are mashed can release more starch and make the texture gluey. Gentle heat and stirring just until combined keeps it fluffy while the butter and milk blend in.
