Preheat oven to 250°F. Grease a large baking sheet.
Mix dry ingredients in a large, shallow bowl. Beat the egg whites
and water in a small bowl.
Dip the nuts into the egg white mixture, one at a time, then roll
in the sugar mixture. Place on the prepared baking sheet and bake
for about 90 minutes or until the coating is dry. Shake off excess
sugar and store in an airtight container.
