Fruit must be packed in a solution of water and sugar or fruit juice. It's up to you which to use. Sugar is added to improve flavor, help stabilize color, and retain the shape of the fruit. It is not added as a preservative. Sugar solution is much less expensive (unless you have a supply of cheap grape juice), so I usually use a light solution to keep sugar (and the added calories) to a minimum.
Yes, honey could be used in place of sugar, but I will warn that it is very sticky and can be messy to work with.
