The thing I like best about this jam is the way the plums stretch the flavor of the raspberries. I make it when plums are in season, and we enjoy it all winter long on toast or homemade bread. For a few years, my husband and I had a small acreage with chickens, rabbits and sheep. Although we now live in town, our hearts still belong in the country! We have six children—three of them grown, two teenagers plus a girl who's 10—and two grandchildren.
In a Dutch oven, combine the plums, raspberries, sugar and lemon juice. Bring to a full rolling boil over high heat, stirring constantly. Stir in pectin. Continue to boil 1 minute, stirring constantly.
Remove from heat; skim off foam. Ladle hot mixture into six hot pint jars, leaving 1/4-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight.
Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 10 minutes. Remove jars and cool.
