1.   Preheat oven to 180c, with racks in upper and lower thirds. Line two baking sheets with parchment paper; set aside. In a medium bowl, whisk together flour, baking soda, salt, ginger, allspice, and pepper.

2.   With an electric mixer, cream butter, brown sugar, and 1/2 cup granulated sugar until light and fluffy. Beat in molasses and egg. With mixer on low, gradually beat in flour mixture until just combined. Flatten into a disk, wrap in plastic, and freeze for 20 minutes.

3.   Divide dough into twelve 2-inch balls. Place remaining 1/3 cup granulated sugar in a bowl. Roll balls in sugar to coat; place at least 4 inches apart on prepared baking sheets. Flatten into 3-inch rounds. Sprinkle with sugar remaining in bowl.

Bake until brown, rotating sheets halfway through, 12 to 15 minutes. Cool cookies on a wire rack.

Note: Freezing the dough for twenty minutes makes it easier to work with. Cookies can be baked up to two days ahead; store in an airtight container at room temperature.
