Step 1

Preheat the oven to 325°F. Lightly oil or coat a rimmed baking sheet with nonstick cooking spray and set aside. For easier clean up, line the baking sheet with aluminum foil and then coat with cooking spray.

Step 2

Whisk together the egg white and water in a large bowl until well blended. Add the walnuts and toss to coat evenly with the egg white mixture.

Step 3

In a separate bowl, whisk together the brown sugar, cinnamon, salt, ginger, and allspice, and sprinkle over the nuts. Toss until well coated.

Step 4

Spread the nuts in a single layer on the prepared baking sheet, and bake until the glaze is crisp and golden brown, 15 minutes. Toss and cook 3 to 5 more minutes until even more golden, as desired. Remove from the oven, toss, and cool completely. Store in an airtight container.
