 * Makes about 95 crackers

Ingredients

 * 1 stick (½ cup) unsalted butter, softened
 * ½ pound pepper jack cheese, grated coarsely
 * 1 large egg, separated
 * 1 teaspoon salt, or to taste
 * ¾ teaspoon cayenne, or to taste
 * 1 cup all-purpose flour

Directions

 * 1) Preheat oven to 375°F and grease two baking sheets.
 * 2) In a food processor blend together butter and cheese until smooth.
 * 3) Add egg yolk, salt, and cayenne and blend until combined.
 * 4) Add flour and blend until mixture just forms a dough.
 * 5) Working in batches, transfer dough to a pastry bag fitted with a ⅞-inch-wide ribbon tip and pipe dough in long strips 2 inches apart on baking sheets. (Alternatively, working in batches, dough may be transferred to a cookie press fitted with a ribbon disk and pressed out in long strips 2 inches apart on baking sheets. Dough strips may break in places but repairs are not necessary, as strips will be cut later.)
 * 6) In a small bowl whisk together egg white and a pinch salt until just combined.
 * 7) Brush each strip of dough with some egg white and bake in batches in middle of oven until golden brown, about 10 to 15 minutes.
 * 8) While crackers are still hot, slice diagonally into 1½-inch-long pieces and cool completely on racks.
 * 9) Crackers keep in airtight containers 5 days.
