Preheat oven to 300°F. Place a piece of parchment paper or a silicone baking mat on a sheet pan.
In a large bowl, whisk together the egg white and cold water until frothy. Stir in the pecans and toss to coat.
Add the sugar, cinnamon, and salt, and stir to combine.
Spread the pecans evenly on the prepared sheet pan. Bake for 30 minutes, stirring halfway through.
Remove from the oven and transfer to a piece of parchment paper (this ensures that the nuts won’t stick to the extra sugar on the bottom of the pan). Let cool and store in an airtight container.

Notes
It is super important to use a piece of parchment paper or a silicone baking mat to line the sheet pan. You do not want to clean caramelized sugar from the bottom of your pan!You can substitute unsalted almonds, walnuts, or cashews for the pecans, if you wish. You may need to alter the baking time slightly for cashews, which burn more easily. Start with 15 minutes, then stir, and bake in 5 minute increments until the nuts are toasted.Want to make these spicy? Add ¼ teaspoon of cayenne pepper along with the cinnamon.
