Ingredients

  • 5 pounds Russet potatoes
  • 1 tablespoon salt
  • 1 to 2 cups whole milk warmed
  • 6 tablespoons butter melted
  • 2 teaspoons bottled truffle oil
  • 1 cup sour cream
  • 4 tablespoons truffle butter divided
  • ½ fresh or jarred truffle grated
  • 1 tablespoon chopped parsley for garnish

Instructions

  • Peel the potatoes and cut into 2-inch uniform chunks.
  • Add the potatoes and the salt to a large pot and cover with cold water.  Bring the water to a boil over high heat, then reduce to a simmer and cook for 20-25 minutes or until the potatoes are very tender.
  • Drain the potatoes in a colander then return them to the pot and place the pot back on the stove top over medium heat.  Cook for 1-2 minutes while shaking the pot until the extra water evaporates and the potatoes are completely dry.  Remove from the heat.
  • Use a potato masher to mash the potatoes; then add 1/2 cup of milk, melted butter, truffle oil and the sour cream.  Stir well then add more milk until you get the desired consistency. 
  • Add 2 tablespoons of the truffle butter and allow it to melt in the hot potatoes, about 30 seconds, then stir into the mashed potatoes. Season to taste.
  • Scoop the mashed potatoes into a serving bowl, add the remaining 2 tablespoons of truffle butter to the top.
  • With a microplane, grate the truffle over the mashed potatoes and garnish with the parsley. Serve hot.

Notes

  • The actual truffle has little flavor. They are not meant to be used like mushrooms.  It is the aromas they share with other foods when used as a garnish that make culinary masterpieces.  
  • Truffle butter, whole preserved truffles and truffle oil are available in the specialty foods sections of some super markets or online.
  • A high starch potato will determine the texture of your mashed potatoes.
  • Russet and Yukon Gold potatoes are high in starch and make great, fluffy mashed potatoes.
  • We like to use Russet potatoes for this recipe as the white flesh produces a nice white contrast mash that shows off the specks of grated truffle.
  • Do not over-work the mashed potatoes. A potato ricer, potato masher or a food mill will give the best results.
  • An electric hand mixer can also be used but be cautious as the potatoes can go from perfect to gluey very quickly.
