• 2 1/2 c. (340 g) sweetened flaked coconut
Preheat oven to 350 degrees.
Place the chocolate in a double boiler to melt. You can make your own double boiler by using a metal bowl that fits over the top of a pan. Fill the pan about one-third full of water and bring to a boil. Once boiling, reduce the heat to medium and place the metal bowl with the chocolate in it on top. Make sure the bottom of the bowl is not touching the water. Stir the chocolate until melted. Avoid overheating it. Once the chocolate is melted, set it aside to cool.
In a mixing bowl, by hand or with the whisk attachment on a stand mixer, stir together the egg whites, cocoa powder, sugar, salt and vanilla. Add the melted chocolate and stir until well blended. Add the coconut and mix until evenly incorporated.
Using a 3/4-oz. portioner, form mounds of the mixture and place on parchment-lined pans. You can also use a spoon to roll the mixture into balls, using about 1 1/2 tablespoons for each. They should be the size of a walnut in the shell. Leave some space between the macaroons for even baking. They will not spread.
