Preheat your oven to 350°F (175°C).

In a food processor, combine the shredded sharp cheddar cheese, all-purpose flour, salt, and unsalted butter. Pulse until crumbly.

Gradually add cold water and a splash of milk until a smooth dough forms.

Transfer the dough to a floured surface and roll it to 1/8 inch thick.

Cut the rolled-out dough into 1-inch squares and poke holes in each square.

Sprinkle with salt and place squares on a parchment-lined baking sheet.

Bake for 12-15 minutes until golden brown and crispy.

Let the crackers cool before transferring to a serving dish.
