Preparation Select fully ripe firm sweet grapes. Sort, stem and wash.
Whole Grapes Prepare same as for regular grapes. Deseeded Grapes Separate pulp, from hulls, saving both. Heat pulp to boiling to separate seed. Mix juice with hulls and boil until the hulls are tender (15 to 20 minutes). Mix softened hulls with deseeded pulp. Add one part sugar to six parts grapes, stirring until sugar is dissolved. Cool and pack, leaving headspace. Seal and freeze.
Grape Juice Prepare same as for regular grapes.
