Canning Strawberry Jelly With Rhubarb
1-1/2 lbs red stalks of rhubarb
1-1/2 qts ripe strawberries
1/2 tsp butter or margarine to reduce foaming (optional)
6 cups sugar
6 oz liquid pectin
Yield: About 7 half-pints
Procedure: Wash and cut rhubarb into 1-inch pieces and blend or grind. Wash, stem, and crush strawberries, one layer at a time, in a saucepan. Place both fruits in a jelly bag or double layer of cheesecloth and gently squeeze out juice. Measure 3-1/2 cups of juice into a large saucepan. Add butter and sugar, thoroughly mixing into juice. Bring to a boil over high heat, stirring constantly. Immediately stir in pectin. Bring to a full rolling boil and boil hard 1 minute, stirring constantly. Remove from heat, quickly skim off foam, and fill sterile jars, leaving 1/4-inch headspace. Wipe rims of jars with a dampened clean paper towel. Adjust lids and process.
