Potatoes, Mashed
Ingredients
Directions
Prepare the potatoes
Boil or steam the potatoes until cooked and mealy.
Remove any discolored spots and place the potatoes in a bowl.
Mash and serve
Beat the potatoes with a wooden spoon for 2-3 minutes, adding salt, butter, and boiling milk or cream.
Continue beating until the mixture is smooth and free of lumps.
Transfer the potatoes to a saucepan and beat over low heat for 1-2 minutes until hot and light.
Dish the potatoes lightly and roughen the surface with a fork.
Optionally, press into a buttered mold and brown in the oven before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that becomes soft, fluffy and mashable when cooked.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Milk or cream
- Adds moisture so the mash becomes smooth and light rather than stiff.
The step that matters
Beat until smooth, then keep the potatoes hot. Overworking starchy potatoes can make them gluey, while under-beating leaves lumps. Beating with hot liquid and gentle heat keeps the starch loose and the mash light and hot.
