Cheese crackers

Ingredients

• •1/2 cup unsalted butter, room temperature
• •1/2 pound sharp cheddar, grated (3 cups)
• •1 large egg
• •1 teaspoon Dijon mustard
• •1 teaspoon fine salt
• •3/4 teaspoon red-pepper flakes
• •1 1/4 cup all-purpose flour, spooned and leveled

Steps

1. 1In a food processor, pulse together butter, cheese, egg, mustard, salt, and red-pepper flakes until smooth. Add flour and pulse until combined. Transfer dough to a work surface and form into a 2-inch-wide log. Wrap in plastic and refrigerate until firm, 4 hours (or up to 1 day).
2. 2Preheat oven to 350 degrees, with racks in upper and lower thirds. Slice dough into 1/4-inch rounds and arrange, 1 inch apart, on two parchment-lined baking sheets. Bake until edges are golden, 15 to 20 minutes, rotating sheets halfway through. Let cool completely on racks before serving.
3. 3Cook's Note Mix It Up: In place of red-pepper flakes, try stirring in 3 tablespoons tomato paste or 1/3 cup crumbled cooked bacon, finely chopped herbs, or finely diced fresh green chiles.
4. 4Store crackers in an airtight container, up to 1 day.
