Grape-Plum Jelly
3-1/2 lbs ripe plums
3 lbs ripe Concord grapes
1 cup water
1/2 tsp butter or margarine to reduce foaming (optional)
8-1/2 cups sugar
1 box (1-3/4 oz) powdered pectin
Yield: About 10 half-pints
Procedure: Wash and pit plums; do not peel. Thoroughly crush the plums and grapes, one layer at a time, in a saucepan with water. Bring to a boil, cover, and simmer 10 minutes. Strain juice through a jelly bag or double layer of cheesecloth. Measure sugar and set aside. Combine 6-1/2 cups of juice with butter and pectin in large saucepan. Bring to a hard boil over high heat, stirring constantly. Add the sugar and return to a full rolling boil. Boil hard for 1 minute, stirring constantly. Remove from heat, quickly skim off foam, and fill sterile jars, leaving 1/4-inch headspace. For more information on how to sterilize jars see "Jars and Lids," (FCS 8255).
Adjust lids and process as recommended in Table 1.
