If using a potato ricer, fill another saucepan with water; place over low heat. Keep potatoes at a low simmer until a knife slips in and out easily. Drain potatoes in a colander. Place milk in a small saucepan over medium-high heat.

2. If using an electric mixer with paddle attachment, proceed to Step 4. If using a potato ricer, place a heat-proof bowl or top of a double boiler over a pan of simmering water. Press hot, drained potatoes through ricer into bowl.

3. Stir potatoes with a wooden spoon until smooth, about 1 minute. Using a whisk, incorporate butter. Drizzle in hot milk, whisking continuously. Add pepper, nutmeg, and salt to taste; whisk to combine. Serve immediately.

4. For the electric-mixer method, transfer hot, drained potatoes to bowl of an electric mixer fitted with the paddle attachment.

Cook's Notes

For stiffer mashed potatoes, use only three-fourths cup milk or cream; for richer potatoes, add another two tablespoons butter.
