The plums are not peeled; this produces a vibrant ruby-red color. This recipe yields approximately 4-8 ounce jars of jam. This is just the perfect amount for DH and me. A food processor is wonderful for processing the plums and if you don't have a water bath don't worry. A large pasta pot with strainer insert works wonders. The recipe comes from Cooking Pleasures.
- 2 1⁄2 lbs plums, finely chopped, unpeeled
- 3 cups sugar
- 3 tablespoons lemon juice
- 1 1⁄2 teaspoons grated fresh ginger
- 1 dash ground allspice
- Place all the ingredients in a heavy large pot; stir to combine.
- Attach a jelly thermometer to side of pan or place a small plate in freezer to chill for testing jam.
- Bring to a rolling boil over medium-high heat, adjusting heat as needed to maintain an even boil; boil for 15 minutes, stirring frequently.
- After 15 minutes of cooking check temperature on thermometer or test small portion of jam on chilled plate, return plate to freezer for 1 to 2 minutes, remove and run finger through sample. When the jam is set you can pull your finger through it and it doesn't run back together. During testing, remove jam from heat.
- As jam sets you will be able to see the bottom of the pot when stirring. The temperature should be about 221 degrees F.
- Pour the hot jam into 4 sterilized 8-ounce jars, carefully wiping jar rims; cover with lids and screw bands.
- Process in boiling water bath for 5 minutes, remove from water bath, allow to cool; check seal.
Wonderful jam! I made it in a slow cooker, and it turned out perfect.
Beautiful purplish color. I like to make with cinnamon instead of allspice.
Love, love, love this recipe. Made it exactly as directed and it turned out perfect. A lovely bright ruby color and I also might have overcooked as it was setting up before I even got it in the jars, but who cares - the taste with the hint of the ginger is spot on and oh so good. Used up all the plums from our tree but I'm thinking of buying more to just have more of this on hand. I continue to use this recipe every year, so good. Think next year I'm going to try it in the slow cooker as another reviewer stated as it does make a mess when boiling all over the counter. But then the taste makes it all worthwhile
