Mashed Potatoes
Ingredients
Directions
Prepare the potatoes
Steam or boil the potatoes until thoroughly cooked.
Drain and shake in the pan over heat to dry them out.
Mash and season
Mash the potatoes thoroughly, ensuring there are no lumps.
Season with salt and butter.
Gradually add milk or cream while beating the potatoes until creamy, smooth, and fluffy.
Use judgment to achieve the right consistency; avoid too much or too little milk.

What each ingredient does
- Potatoes
- Provide the starch that gives mashed potatoes their bulk and fluffy texture.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Milk or cream
- Adds moisture and fat, loosening the mash to a creamy consistency.
The step that matters
Adding the milk or cream. Adding liquid gradually while beating lets the starch absorb it evenly. Too much liquid makes the mash loose and runny, while too little leaves it stiff and dry.
