Combine onion with water and set aside for 5 minutes. Cook onion and celery in butter/margarine until onions tender but not brown, about 5 minutes. In a large bowl, toss onion mix with bread cubes to mix well. Combine remaining ingredients in hot water and pour over bread, tossing lightly as needed. If a more moist dressing needed, add up to another 1/2 cup water. From "Canadian Spice Manual and Cookbook" , Canadian Spice Association.
