Mustard Cheddar Crackers

DIRECTIONS

• A food processor makes this come together in a snap but the dough can be made by hand.
• Blend together until smooth the butter, cheese and egg yolk.
• Add remaining ingredients and pulse until just blended. (If your food processor is small, you may have to do this in batches.). Transfer dough (it will be very soft) to a bowl and chill for 15 minutes.
• Halve dough and on a lightly floured surface, shape each half into a 12-inch log.
• Wrap logs in waxed paper then in foil and chill until firm, at least 4 hours. If you plan to freeze them, now is the time.
• Place oven racks in upper and lower thirds of oven. Preheat oven to 350ºF. Line 2 large baking sheets with parchment paper.
• Unwrap logs and with a sharp, thin knife cut into 1/8-inch-thick slices. Arrange slices 1-inch apart on baking sheets.
• Bake in batches, switching position of sheets halfway through, baking until golden brown, 12-15 minutes.
• Transfer to racks to cool. Line sheets with clean parchment between batches.
• Crackers, cooled completely, keep in a airtight container at room temp 1 week.
