Mashed Potatoes

INGREDIENTS

1. 3 lb. mixed potatoes, such as russets and Yukon Golds
2. Kosher salt
3. 1/2 c. (1 stick) butter, plus 2 tablespoons for garnish
4. 1/2 c. milk
5. 1/2 c. sour cream
6. Freshly ground black pepper

DIRECTIONS

In a large pot, cover potatoes with water and add a generous pinch of salt. Bring to a boil and cook until totally soft, 16 to 18 minutes. Drain and return potatoes to pot.

Use a potato masher to mash potatoes until smooth.

Meanwhile, in a small saucepan, melt butter and milk until warm.

Pour over warm milk-butter mixture and stir until completely combined and creamy. Add sour cream and stir until combined.

Season mashed potatoes generously with salt and pepper.

Transfer potatoes to a serving bowl and top with remaining two tablespoons butter. Season with more pepper before serving.
