This makes a large batch of nuts, which you can freeze, give away as gifts, use in appetizers, salads, on side dishes, or even as a topping on a dessert or ice cream.
Place pecans in a large bowl. In a separate bowl, mix together sugar, cinnamon, nutmeg, salt, and cayenne.
Beat the egg white and water until frothy. Pour egg mixture over pecans and toss to coat. Pour the dry ingredients onto the pecans and toss again until evenly coated.
Spread evenly in a roasting pan and bake for 1 1/2 hours.
Allow to cool, stirring occasionally so pieces don’t clump together. Store at room temperature in an airtight container up to 1 months.
