Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch that breaks down into a soft, fluffy body when mashed.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Milk
- Adds moisture that loosens the mash and makes it creamy.
The step that matters
Drying the potatoes after draining. Returning the drained potatoes to the heat evaporates surface water. Wet potatoes turn gluey and dilute the butter and milk, so a short dry gives a fluffier mash.
