Preheat oven to 300 degrees F.

Line a large baking sheet with parchment paper and set aside.

In a medium bowl, add sugar, cinnamon, and salt. Mix until combined. Set aside.

In a large bowl, whisk the egg white, vanilla, and water together until frothy. Add the pecans and gently toss until the pecans are well coated. Add the sugar and cinnamon mixture and toss until pecans are covered.

Spread the pecans in a single layer on the prepared baking sheet.

Bake for about 40-45 minutes, turning every 15 minutes. The sugar mixture will harden on the pecans.

Remove from the oven and let the pecans cool on the baking sheet. When completely cool, store in an airtight container for up to 3-4 weeks.
