Wash and core tomatoes and then pour into blender. Add other ingredients and blend together until smooth. Pour on a strainer to remove any pulp.
Transfer smooth puree to a large kettle and bring to a boil over medium heat for 5 hours with kettle uncovered. Stir frequently to avoid scorching.
When mixture is thick; spread on 5 fruit roll sheets. Place sheets on trays and then set in the dehydrator. Dehydrate at 140°F (60°C) until dry and crispy.
