In a pot put some water on a low-medium heat. On that pot put a mixing bowl. Add the egg whites along with the sugar. Stir continuously for a couple of minutes to dissolve the sugar but make sure the egg does start cooking.
Now add butter and mix well. In that mixture add coconut and mix it altogether using your hand.
Once the mixture is all done, using a medium sized scoop, scoop out the mixture and make balls. Cover the baking tray with parchment paper and place the coconut balls on the tray spaced about an inch apart. Cut the maraschino cherries in half and put it on the coconut balls.
Heat the convectional oven at 300F and place the tray in the oven and bake it for 10-15 mins or until the coconut has a color. Baking time varies depending on the oven.
