Preheat oven to 325℉ (162℃)
Prepare 2 sheet pans by lining with parchment paper or silicone baking mats.
Place egg whites and salt in the bowl of a stand mixer (a hand mixer may also be used) and allow to come to room temperature.
3 Large Egg Whites, ½ teaspoon Salt
In a separate large bowl, combine granulated sugar, vanilla extract, coconut and applesauce. Set aside for later.
3 Cups Shredded Coconut, ¾ Cup Granulated Sugar, 1 teaspoon Pure Vanilla Extract, 2 Tablespoon Unsweetened Applesauce
Begin mixing the egg whites on low speed. Slowly increase the speed to medium-high and continue mixing until egg whites hold a medium peak. Note - A medium peak stands up with a slight curl at the tip when you lift the whisk.
Gently fold the egg whites into the bowl with the coconut mixture, being careful not to overmix, as this can deflate the egg whites and reduce the cookies' lightness.
Using a cookie scoop or tablespoon, drop about 1 tablespoon of the macaroon batter onto the prepared sheet pan, leaving approximately 1½ inches between each macaroon.
Bake for 14 - 18 minutes (tops will be a golden brown).
Cool on sheet pans for 5 minutes then move macaroons to a cooling rack to cool completely.
