In a small bowl, whisk the egg white until frothy. Stir in the sugars, cinnamon, salt, and 1/4 cup water. Put in the nuts and stir gently to coat well. Pour into the crock and cook on high 3 hours stirring once in a while. Be gentle, don't break the nuts. After 3 hours, turn off crock and stir in 1/4 cup water. Heat oven to 375. Line a large baking sheet with parchment paper and spread the nuts in an even layer. Bake for 10 minutes (don't stir). Remove from oven and let cool completely on pan. When cool, break apart and store in an airtight container.
