Plum Jam Recipe (No Peel, No Pectin!)

Steps

1. Place pitted and halved plums into the mixing bowl & drizzle with 4 1/2 cups of sugar. Stir plums until all coated with sugar. Let them sit for 1 hour then transfer the mixture into a large cooking pot.

2. Bring it to a boil uncovered, stirring occasionally. Boil until the mixture is bubbling uniformly. Simmer for 10 minutes then turn off the heat. Cool to room temperature.

3. Repeat step 2 a total of FOUR times. Last time bringing it to a boil at the lower temperature, stirring frequently to prevent scorching.

4. Start by washing your jars and lids with warm water and soap then let them dry in the oven at 215 for about 20 min or until completely dry. Boil the lids 5 min.

5. Transfer your boiling hot jam to the jars using a glass measuring cup and a funnel (least messy method) leaving about 1/2″ space.

6. Screw the lids on enough to keep a tight seal in place but don't over-tighten them since air bubbles need to be able to escape.

7. Place packed cans into the canning pot and cover with 1-2 inches of water. Bring to a boil and process 15 minutes. Remove from the pot and leave at room temperature undisturbed for 12-24 hours. You may hear a pop when the jars fully seal. After 24 hours, check that the seal has formed by pushing down on the center of the lid - it should not move at all. If the seal does not form, refrigerate jam and enjoy within 3 months.
