Hickory Nut Cookies

Preheat oven to 300°F. Coat 3 baking sheets with nonstick cooking spray. (Or use 1 baking sheet and wash and respray between batches.) Melt butter in a small saucepan over medium heat. Add nuts and stir until the butter is lightly browned, about 1 minute. Transfer to a mixing bowl. Stir in granulated and brown sugars. Add egg whites, flour and vanilla; whisk until combined. Working with one baking sheet at a time, spoon a heaping teaspoon of batter to make a line about 8 inches long and 3/4 inch wide. Repeat to make 8 lines on the sheet, spacing them about 1 inch apart. Bake until the cookies are well-browned on the edges, 8 to 10 minutes. Working quickly using a metal spatula, remove a cookie and wrap it around a 3/4-inch-thick wooden dowel or fat wooden spoon handle. Once the cookie stiffens, slide it off and repeat with the next cookie. If the unshaped cookies begin to harden and stick to the pan, return the baking sheet to the oven for about 30 seconds to soften them. Bake and shape the remaining batter in the same manner.
