Ingredients
  

Roasted garlic
  • 2 large heads garlic tops trimmed
  • 1 tablespoon olive oil
  • 1/4 teaspoon kosher salt
Potatoes
  • 3 pounds Yukon Gold potatoes peeled if desired and cut into 1 1/2-inch chunks (1.35 kg)
  • 1 tablespoon kosher salt for the cooking water
  • 6 tablespoons unsalted butter softened (85 g)
  • 3/4 cup heavy cream or whole milk warmed (180 ml)
  • 1/3 cup sour cream 80 g
  • 1 teaspoon kosher salt plus more to taste
  • 1/2 teaspoon white or black pepper
To finish
  • 2 tablespoons fresh chives chopped
  • 1 tablespoon butter for the top

Method
 

Roast the garlic
  1. Preheat the oven to 400°F (200°C). Trim the tops off the garlic heads, drizzle with oil and salt, wrap in foil and roast for 40 to 45 minutes until soft. Cool, squeeze out the cloves and mash.
Cook the potatoes
  1. Cover the potatoes with cold water and 1 tablespoon of salt. Bring to a boil and cook for 15 to 20 minutes until very tender.
  2. Drain and return to the hot pot over low heat for 1 to 2 minutes to steam dry.
Mash
  1. Warm the cream and butter together until the butter melts.
  2. Mash the potatoes until smooth, then fold in the roasted garlic, the warm cream mixture, the sour cream, salt and pepper.
  3. Top with butter and chives and serve hot.
Make ahead
  1. Cool quickly and refrigerate in a baking dish for up to 2 days. Reheat covered at 350°F (175°C) for 35 to 45 minutes, stirring once and adding a splash of cream.

Notes

Make ahead: Mash up to 2 days ahead. Reheat in the oven or keep warm in a slow cooker on low for up to 2 hours.
