Yield: About 8 or 9 half-pint jars
Procedure: Sterilize canning jars and prepare two-piece canning lids according to manufacturer's directions.
To prepare fruit. Sort and wash grapes; remove from stems. Slip skins from grapes; save skins. Measure skinned grapes into a kettle and boil, stirring constantly, for about 10 minutes, or until seeds show. Press through a sieve to remove seeds. Chop orange fine without peeling it.
To make conserve. Add orange, sugar, raisins, and salt to sieved grapes. Boil rapidly, stirring constantly, until the mixture begins to thicken (about 10 minutes). Add grape skins and boil, stirring constantly, to 9 degrees F. above the boiling point of water (about 10 minutes). Do not overcook; the mixture will thicken more on cooling. Add nuts and stir well. Remove from heat; skim.
Fill hot conserve immediately into hot, sterile jars, leaving ¼ inch headspace. Wipe rims of jars with a dampened clean paper towel; adjust two-piece metal canning lids. Process in a Boiling Water Canner.
