0 Preheat oven to [wprm-temperature value="300" unit="F"] and prepare a baking sheet with parchment paper.
1 In a large bowl, whisk together the egg whites, water, and vanilla extract until frothy. Add the pecan halves and toss until they're well coated.
2 In another small bowl, whisk together the granulated sugar, brown sugar, ground cinnamon, salt, and ground nutmeg. Add to the pecans and toss again.
3 Pour coated pecans onto the baking sheet and spread out into an even layer. Bake for 30 to 40 minutes, and stir to re-coat every 10 minutes. Remove from the oven and allow to cool completely before storing or serving.
