Line two baking sheets with parchment paper and set aside.
In a small saucepan combine 3 tbsp water, 2/3 cup granulated sugar, 1 tbsp light corn syrup, and 1/2 tsp salt.
Heat the saucepan over medium-high heat and bring the mixture to a boil, stirring frequently until the sugar dissolves. Remove from heat as soon as it reaches a boil.
Place 14 oz sweetened shredded coconut in a medium heatproof bowl. Pour the hot syrup over the coconut and stir until the coconut is evenly coated. Let the coconut mixture cool for 20 minutes.
While the coconut mixture cools (or immediately after), preheat the oven to 350°F and keep the prepared baking sheets ready.
In a separate bowl, combine 2 room-temperature egg whites and 1 tsp vanilla extract. Whisk by hand or with an electric mixer until the egg whites are foamy and slightly thickened.
Gently fold the cooled coconut mixture into the whisked egg whites until evenly combined.
Use a cookie scoop to portion golf-ball-sized mounds of the mixture onto the prepared baking sheets, spacing the macaroons about 2 inches apart.
Bake in the preheated 350°F oven for 14–18 minutes, rotating the baking sheet halfway through if your oven bakes unevenly, until the macaroons are golden brown.
Remove the baking sheets from the oven and place them on wire racks to cool completely.
Once cooled, store the macaroons in an airtight container.
