Recipe adapted from The Lee Bros. (via Smitten Kitchen)
1 1/2 cups (about 6 ounces) grated extra-sharp Cheddar cheese
4 tablespoons (1/2 stick or 2 ounces) unsalted butter, softened and cut into 4 pieces
3/4 cup flour, plus more for dusting
1/2 teaspoon kosher salt
1 1/2 teaspoon freshly ground pepper
1 tablespoon half-and-half
Preheat oven to 350°F.
In a food processor, combine the cheese, butter, flour, salt and pepper in five 5-second pulses until the mixture resembles coarse crumbs. Add the half-and-half and process until the dough forms a ball, about 10 seconds.
On a lightly floured surface, using a lightly floured rolling pin, roll the dough roughly into a 13 by 7-inch rectangle that is 1/16-inch thick. With a pastry wheel, trim off the sides into a 12 by 6-inch rectangle. Next, cut the dough into 1 by 1-inch squares. Using the blunt end of a skewer make a hole in each cracker. Gently transfer the crackers (I needed to use a sharp knife to get them off the table) to a parchment lined baking sheet. The dough may sag or may break occasionally in the transfer, but don’t be concerned — just do your best.
Bake the crackers on the middle rack for 15 minutes, or until the ends are barely browned. Remove from the oven and set the baking sheet on a rack to cool.
Serve at room temperature.
