Preheat oven to 300° F.

In a large mixing bowl, combine sugar and salt.

In a separate mixing bowl, whisk together egg whites, water, and vanilla extract.

Pour pecans into egg mixture and toss to coat.

Pour coated pecans into sugar mixture and mix well to coat.

Spread pecans on a rimmed baking sheet lined with parchment paper or aluminum foil.

Bake at 300° for 20 minutes. Stir; then bake for another 15-20 minutes, until a bubbly white coating has formed on the pecans.

Remove from oven; set pan aside to cool.

Once cooled, break pecans apart and store in an airtight container at room temperature.
