Preheat the oven to 300 degrees. Line a baking sheet with parchment paper and coat with cooking spray. Set aside.
In a small bowl, mix both sugars, salt, cinnamon, cayenne pepper, nutmeg and cloves until well combined.
In a separate medium-sized bowl, whisk the egg white until foamy. (Not beaten into a stiff merengue, but just until it is lightened up and bubbly.) Add the pecan halves to the egg white and stir until each pecan is completely moistened with the egg white.
Add the sugar and spice mixture to the nuts and stir until the pecans are evenly coated. Transfer the pecans to the prepared baking sheet. Separate any nuts that are sticking to each other and spread into an even layer.
Bake for 30 minutes, stirring the nuts after 15 minutes and every 5 minutes thereafter. Remove the nuts from the oven and allow them to cool on the baking sheet to room temperature. (Don’t worry if the nuts still seem damp, they will become crispy as they cool.)
Once the nuts have cooled, separate any nuts that are stuck together. Start munching!
Notes
Toss with some dark chocolate chips and homemade granola for a delicious trail mix!
