Preheat the oven to 300°F (150°C). Line a large rimmed baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, whisk the egg white and water together until frothy and slightly thickened, about 30–60 seconds. If using aquafaba instead of egg white, whisk it in the same way until foamy.
1 large egg white, 2 tablespoons water
Add the brown sugar, maple syrup, molasses, and vanilla extract to the bowl. Whisk until the sugar is mostly dissolved and the mixture looks glossy and smooth.
1/3 cup brown sugar, 3 tablespoons pure maple syrup, 1 tablespoon molasses, 1 teaspoon pure vanilla extract
Whisk in the ground ginger, ground cinnamon, ground cloves, ground nutmeg, ground allspice (if using), and fine sea salt until evenly combined.
2 teaspoons ground ginger, 2 teaspoons ground cinnamon, 1/4 teaspoon ground cloves, 1/4 teaspoon ground nutmeg, 1/4 teaspoon ground allspice, 3/4 teaspoon fine sea salt
Add the mixed raw nuts to the bowl. Using a spatula or wooden spoon, stir slowly but thoroughly until every nut is evenly coated with the spiced mixture.
4 cups mixed raw nuts
Pour the coated nuts onto the prepared baking sheet and spread into as even a single layer as possible. Some nuts may touch and stick together; that is fine.
Bake for 30–35 minutes, stirring every 10 minutes and spreading the nuts back into an even layer after each stir. The glaze should look dry and set, and the nuts should smell fragrant and toasty.
During the last 5–10 minutes of baking, if desired, sprinkle the nuts with granulated sugar, give a quick toss, and return to the oven to finish baking.
2 tablespoons granulated sugar
Remove the baking sheet from the oven. The nuts will still feel a bit soft while hot. Let them cool completely on the pan; they will firm up and become crunchy as they cool. After 10–15 minutes, gently break apart any large clusters.
Once fully cool, taste and, if desired, sprinkle with a tiny pinch of additional salt and toss. Store in an airtight container once completely cooled.
