3/4 cupraw (demerara/turbinado) sugar, or to taste
1 tablespoonmatcha (unsweetened green tea powder)
1/4 teaspoonfine sea salt
1large egg white, at room temperature
1 tablespoonwater
1 pound(about 4 cups) raw walnut halves
Instructions
Preheat the oven to 300º F and line a baking sheet with parchment paper. In a small bowl, whisk together sugar, matcha, and salt. Set aside.
In a large mixing bowl, whisk together egg white and water until thick and foamy but not stiff. Add nuts and stir to coat evenly. Sprinkle the sugar mixture over the nuts, and toss again until evenly coated.
Spread the nuts in a single layer on the baking sheet. Bake, stirring every 10 minutes or so, for about 30 minutes, or until the nuts are deeply browned and just dry to the touch. Remove from the oven and let cool completely on the baking sheet.
Once the nuts are cooled, go through and break up any stuck-together clumps. Transfer to an airtight container and store at room temperature for up to 2 weeks.
