Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that becomes soft and fluffy when mashed.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Hot cream
- Adds moisture and richness, and keeps the mash smooth and loose when hot.
The step that matters
Drying the potatoes after draining. Shaking the pan over the heat evaporates surface water so the mash absorbs the butter and cream rather than turning wet and gluey.
