Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment paper.

Whisk egg white and water in a large bowl until frothy. Add pecans and stir until evenly coated.

Mix sugar, cinnamon, salt, cloves, and nutmeg in a small bowl; sprinkle over moistened nuts. Spread pecans in a single layer on the prepared baking sheet.

Bake in the preheated oven, stirring once or twice, until toasted and fragrant, about 30 minutes. Let cool completely on the pan; nuts will crisp as they cool.

Remove from oven and cool completely on the baking sheet before serving or storing in an airtight container at room temperature for up to 2 weeks.
