Preheat your oven to 300°F.

Prepare a rimmed baking sheet by lining it with parchment paper. This is not necessary, but it makes clean up a snap!

In a small mixing bowl, combine the white sugar, brown sugar, cinnamon, and salt. Use a whisk or your hands to break up clumps in the brown sugar.

You can use a stand mixer, hand mixer, or just a whisk for the next part. I use my stand mixer because it’s easier and faster.

Whisk the egg white, water, and the vanilla extract until it’s really light and fluffy. Fluffy like a cloud.

Toss in the pecan halves and stir them into the fluffy cloud of egg white until they are all well coated with the mixture.

Then, pour in the cinnamon sugar mixture. Mix again until all the pecans are well coated with sugar.

You will probably need to use your hands to pull some of the pecans halves apart. They tend to stick together and you want them to be well coated on both sides with the sugar.

Pour the coated pecans out onto your parchment paper lined tray. Arrange them so that they are in a single layer as much as possible.

Now slide them into your preheated oven.

These guys need to bake for a total of 30 to 45 minutes. Every 15 minutes or so you need to pull them out and stir them all around. This breaks any up pecans that are sticking together.

They are done when the cinnamon sugar has hardened on the pecans.

Let cool on a wire rack before eating. The cinnamon sugar mixture will be HOT. So contain your excitement for about 5 minutes or so before you start snacking.
