2. Spread 2 cups coconut on a baking sheet, then toast in oven until just beginning to brown, about 5 minutes; transfer to a plate and set aside to cool.
3. Whisk egg whites, sugar, vanilla, and salt in a large bowl until sugar is mostly dissolved. Add toasted coconut and remaining untoasted coconut and stir until combined.
4. Scoop heaping tablespoons of mixture onto a parchment-lined baking sheet, spacing them about 1/2" apart. Transfer to oven and bake until tops of macaroons are golden brown, 20 to 25 minutes. Let cool completely on baking sheet. Store macaroons in an airtight container for up to five days.
