Preheat oven to 250° F.

Whip egg white and water in a mixing bowl until frothy. In a separate bowl, combine sugar, salt, and cinnamon.

Toss pecans in egg white mixture and stir to coat evenly. Remove pecans from egg white mixture, pour into sugar mixture and toss to coat. Spread pecans on a greased baking sheet.

Bake until nuts are toasted and fully glazed, about 1 hour. Stir every 15 minutes. Cool thoroughly. Break into pieces if necessary.
