Spray your crock-pot with the cooking spray.
Add the egg white to your slow cooker, and beat with a fork until frothy.
Add everything but the nuts, and stir until you have a thick, syrup.
Add the nuts, gently stir to coat, and cook on low for two and a half hours.
Stir the nuts every hour ensure they cook evenly.
When they are done cooking place the nuts evenly on a silpat mat and allow them to cool.
