Preheat oven to 300 degrees F. Line a large baking sheet with parchment paper.

Wet coating: in a mixing bowl beat egg white, vanilla, and water until stiff peaks form.

Dry coating: Add granulated sugar, brown sugar, cinnamon, and salt to a bowl and stir to combine.

Add pecans to the egg whites mixture and gently toss to coat. Add the cinnamon sugar mixture and stir gently until the pecans are well coated.

Bake: Spread the pecans into a single layer on the prepared baking sheet. Bake for about 40-45 minutes, stirring every 15 minutes. Remove from the oven and allow the pecans to cool completely on the baking sheet.

Store candied pecans in an airtight container at room temperature or in the refrigerator for several weeks.
