Method

  • Preheat the oven to 400 degrees F.

  • Roast until golden, about 4 to 6 minutes.
  • Remove from the oven and cool.
  • Using a small food processor, grind the nuts.
  • Cream the butter and sugar in the bowl of an electric mixer filled with a paddle on medium speed, scraping down the sides of the bowl as necessary.
  • Cream the mixture until it is smooth and fluffy.
  • Add the egg yolks 1 at a time, mixing in between each addition.
  • Scrape down the sides of the bowl.

  • Add to the butter mixture and mix on low speed until it is fully incorporated.
  • Increase the speed to medium and mix until the batter is thick and creamy, about 2 minutes.
  • Scrape down the sides of the bowl and paddle.
  • Generously dust a large sheet of parchment or waxed paper with flour.
  • Spoon the dough down the center of the paper, fold the paper tightly over the dough, and roll into a cylinder about 3 inches in diameter and 12 to 14 inches long.
  • Refrigerate for 8 hours.
  • Reduce the heat of the oven to 350 degrees F.
  • Line a baking sheet with parchment or waxed paper.
  • Remove the dough from the refrigerator and peel away the paper.

  • Place them on the baking sheet about 2 inches apart.
  • Bake until lightly golden, about 20 minutes.
  • Remove the cookies from the oven and let cool completely in the pan.
