Don’t just skip over this post because it’s homemade jam, & canning is hard or whatever. Seriously, until you have had homemade plum jam, you have not lived! Growing up we had a plum tree in our yard & my mom would make plum jam every year until we cut the tree down. I loved it then, & I forgot how good it was until now. One of my husband’s classmates brought us some plums from his tree & so I made some jam. My kids are already scarfing it down. They can’t get enough PB&J sandwiches or toast with jam.
Plums have this sweet yet tangy flavor to them that really pops on your taste buds. So even though I saw this huge bag of plums that my husband brought home, & wondered, “What in the heck am I going to do with all these before they go bad?” I am so glad I decided to make them into jam. Now all I need is fresh bread out of the oven to spread my jam on! Yum!
INCREASE processing time:

- LADLE hot jam into hot jars, one at a time, leaving ¼ inch headspace. Wipe rims. Center lids on jars. Apply bands & adjust to fingertip tight.
- PLACE filled jars in canner ensuring jars are covered by 1 to 2 inches of water. Place lid on canner. Bring water to gentle, steady boil.
- PROCESS jars for 10 minutes, adjusting for altitude*. Turn off heat, remove lid & let jars stand for 5 minutes.
- REMOVE jars & cool. Check lids for seal after 24 hours. Lid should not flex up & down when center is pressed. Clean & store jars according to manufacturer's instructions.
- *To enjoy now: LADLE hot jam into hot jars. Cool to room temperature, about 30 minutes. REFRIGERATE jam or serve immediately. Refrigerate for up to 3 weeks.
