Preheat your oven to 250 degrees. Spray a baking sheet lightly with oil.
Whisk together the egg white and water in a mixing bowl until frothy. Add a few drops of vanilla and whisk to mix in. In a wide, flat bowl, mix together the sugar, salt, cloves, nutmeg and cinnamon. Add pecans to egg whites and stir to coat them evenly. Remove the nuts with a slotted spoon, and roll them in the sugar mixture until coated--this is easiest to do in small batches.
Spread the nuts out on the prepared baking sheet so they do not touch each other and put into the preheated oven. Bake for 1 hour. Let cool before serving or tasting--they are hot inside when they come out of the oven!
