How do I make it ?
Slip skins from grapes. Finely chop skins; set aside. Combine grape pulp and water in saucepan. Bring to boil; cover. Simmer 5 min. Press cooked pulp through sieve to remove seeds. Combine pulp and skins. Measure exactly 7-1/4 cups prepared grapes into large saucepan. Combine 1/4 cup sugar and pectin crystals. Add to grapes; mix well.
Bring to full rolling boil on high heat, stirring constantly. Add remaining sugar; stir. Return to full rolling boil; cook 1 min., stirring constantly. Remove from heat. Stir and skim foam for 5 min. to prevent fruit from floating to surface.
Pour immediately into warm sterilized jars, filling to within 1/4 inch of rims. Cover with lids. Let stand at room temperature 24 hours or until set.
