1. Preheat the oven to 300 degrees F. Line a baking sheet with parchment paper.
  2. Cream the butter with the sugar until light and fluffy. Add the black pepper, pinch of salt, and honey; mix to incorporate. Add the nuts and flour, and mix with the electric mixer until the dough forms moist clumps, a few minutes.
  3. Roll large teaspoonfuls of the batter between your clean hands, to make little balls. Place the balls on the baking sheet, and press down on them twice with the tines of a fork to make a crosshatch pattern. Sprinkle with a little bit of granulated sugar. Bake the cookies for 25 minutes, or until their bottoms have turned golden-nutty brown. Set aside to cool before eating.
