Ingredients
- 1 1/2 tablespoons whole black peppercorns, ground
- *if you, like us, aren't blessed with the room to hold a spice grinder, just go with 1 1/4 tbs black pepper
- 4 cups all-purpose flour plus additional for dusting
- 2 teaspoons baking powder
- 2 teaspoons salt
- 4 1/2 ounces Parmigiano-Reggiano, finely grated (2 1/4 cups)
- *we ran out of parmesan, so we used Pecorino to make up the difference (a bit more than 1/4 cup)
- 1 1/2 sticks (3/4 cup) cold unsalted butter, cut into 1/2-inch cubes
- 4 large eggs
- 1 cup whole milk
Directions
- Put oven racks in upper and lower thirds of oven and preheat oven to 350°F.
- Pulse peppercorns in grinder until coarsely ground.
- Whisk together flour, baking powder, salt, 2 cups cheese, and 1 tablespoon ground black pepper in a large bowl.
- Blend in butter with a pastry blender (if you don't own one of these either, do what we did and use your fingertips) until mixture resembles coarse meal.
- Whisk 3 eggs with milk and add to flour mixture, stirring with a fork until a soft dough forms.
- Divide dough into four pieces. On a floured surface with well-floured hands, form each piece into a slightly flattened 12-inch-long log (about 2 inches wide and 3/4 inch high). Transfer logs to 2 ungreased large baking sheets, arranging logs about 3 inches apart.
- Whisk remaining egg and brush some over logs, then sprinkle tops of logs evenly with remaining 1/4 cup cheese and 1/2 tablespoon ground pepper.
- Bake, rotating sheets 180 degrees and switching position of sheets halfway through baking, until logs are pale golden and firm, about 30 minutes total.
- Cool logs to warm on sheets on a rack, about 10 minutes. Reduce oven temperature to 300°F.
- Carefully transfer 1 warm log to a cutting board and cut diagonally into 1/2-inch-thick slices with a serrated knife. Arrange slices, cut sides down, in 1 layer on a baking sheet. Repeat with remaining logs, transferring slices to sheets.
- Bake, turning over once, until golden and crisp, 35 to 45 minutes total. Cool biscotti on baking sheets on racks, about 15 minutes.
