What each ingredient does
- Potatoes
- Starch that breaks down into the fluffy, light body of the mash.
- Hot milk
- Adds moisture and creaminess, and hot liquid keeps the mash smooth and loose.
- Butter or oleomargarine
- Adds fat for richness and a silky mouthfeel.
The step that matters
Mashing the potatoes until very light. Overworking warm potato starch releases excess starch and makes the mash gummy and sticky. Mash gently and add the liquid and fat while the potatoes are hot so they absorb them evenly without becoming dense.
