If you or your neighbor has a rhubarb patch, you may be hard pressed to make use of an abundant crop. Don’t overlook its possibilities in preserves. Rhubarb adds a pleasant tartness to this jam, and the blueberries provide color and texture. —Lanza’s Country Inn, Livingston Manor, New York

In a large kettle crush the blueberries, then add the rhubarb, lemon juice, and sugar. Bring the mixture to a rolling boil for 1 minute. Remove from heat, add the pectin, and stir well. Ladle the jam into sterile jars, seal, and process in a hot-water bath for 15 minutes.
