Classic Mashed Potatoes

4 lbs Yukon Gold potatoes, peeled and cut into 1-inch pieces
Salt and pepper
1 cup heavy cream
1 cup whole milk
4 oz (1 stick) unsalted butter

Place potatoes and 2 tbsp salt in a large sauce pan. Cover with cold water by 2 inches and bring to a boil. Reduce heat to medium-low, and simmer until tender, 8-10 mins.

Meanwhile, heat cream, milk and butter in a small saucepan over medium-low heat, stirring occasionally, until butter melts.

Drain potatoes and mash until smooth. Pour warmed cream mixture over potatoes in a slow, steady stream, and stir until smooth. Season with salt and pepper. Serve immediately or keep in a covered bowl over simmering water for up to 2 hours.
