• Half and pit all of the plums then run the plums through your food processor. 
• In a large sauce pan, combine plums, water, lemon juice, spices and sugar. Bring to a boil over medium-high heat, stirring frequently. Reduce heat and boil gently until mixture thickens and holds its shape on a spoon 30-40 minutes. 

For Canning:

• Prepare your canning supplies; sterilize the canning jars by running them in almost boiling water for several minutes, and boil a few cups of water in a small saucepan for the lids. Ladle hot butter into hot jars, leaving 1/4″headspace. Wipe rim and center lids on jars, and then screw down bands just until resistance is met. Place jars in canner, ensuring they are covered with water, and boil for 10 minutes. Remove canner lid and wait 5 more minutes before removing jars.
