Preheat oven to 250ºF with the oven rack in the middle. Line a rimmed baking sheet with parchment paper.

In a medium mixing bowl, combine the egg whites, coconut sugar, maple syrup and salt. Whisk to combine. Add in the nuts, and toss until they're evenly coated.

Spread the candied nuts in an even layer on the rimmed baking sheet. Bake for 1 hour, toss the nuts half way thru.

Remove from the oven and allow to cook completely, at least 15 minutes. When you take the nuts out they'll still seem "soft". Don't worry, they crisp up after they cool. Break the nuts apart and serve.

Will keep in an airtight container for 2 weeks.
