Ingredients

  • 3 oz Point Reyes Toma or other artisanal semi-hard cheese
  • 2 lbs fingerling potatoes
  • pound Yukon Gold potatoes
  • 5 oz 10 tablespoons unsalted butter
  • 1 pint buttermilk
  • Balinese Truffle Salt

Instructions

Prep

  • Cut the Yukon Gold potatoes into 1-inch pieces.
  • Peel and cut the fingerling potatoes into 1-inch pieces.
  • Grate the Toma.
  • Dice the butter.

How to Cook

  • In a large pot, cover the potatoes with cold water.
  • Add a pinch of kosher salt and turn the heat to medium-high. Bring to a simmer, then adjust the heat to maintain a simmer until the potatoes are tender.
  • Drain, then return the potatoes to the pot. Use a spoon to crush.
  • Turn the heat to low and stir with a whisk until the potatoes dry slightly.
  • Slowly add the buttermilk, stirring continuously to emulsify.
  • Whisk in the butter and whip the potatoes until smooth.
  • BONUS: Saute your favorite ButcherBox sausage and fold it in!
  • Taste and adjust the seasoning with Balinese Truffle Salt.
  • Transfer the potatoes into a casserole dish and top with the grated cheese.
  • If serving immediately, set your broiler to high and broil, uncovered, until golden brown, about 4 minutes. If storing, set aside to allow the potatoes to come to room temperature, then cover with aluminum foil and store in your refrigerator, ready to reheat for Turkey Day!

Reheating Instructions

  • Preheat your oven to 400F.
  • Bake, covered with the aluminum foil, until warmed through, about 20 minutes.
  • Remove the foil and turn your oven to broil and broil until GBD (Golden Brown & Delicious). Finish with a final sprinkle of Balinese Truffle Salt.
