How to Make It
Preheat oven to 250°F.
Whisk together brown sugar, egg white, salt, vanilla, and cinnamon in a large bowl. Add nuts; toss to coat. Spread nut mixture in a single layer on a parchment paper-lined baking sheet. Bake at 250°F until crisp and toasted, about 50 minutes, stirring every 15 minutes. Remove from oven; cool completely. Store nuts in an airtight container up to 1 week.
