Plum and orange are flavors that pair very well together. Having our own plum trees I am always looking for ways to add variety to our pantry with various plum recipes. Plums and oranges are a combination that I love so much so this plum orange jam is absolutely delightful and a joy to add to my pantry. Not only is it sweet, a must for me, but it also has that citrus fresh taste. I really enjoy figuring out how many lovely recipes I can come up with to can for my pantry from the fruit blessings we’ve been given.
Plum Orange Jam
Start by preparing your boiling water bath with enough water to cover 6 half-pint jars with 1-2 inches of water. Place the water bath canner on the stove on medium heat. Next, preheat your jars in the oven at 250 degrees Fahrenheit. Then, submerge your canning lids in a small pan of water, bring it to a boil, and then leave it at a simmer. Now that your equipment is ready, it is time to start canning jam.
Making the Plum Orange Jam
Wash, de-stem, pit, and chop 5 cups of plums. (about 3.5 pounds)
add all ingredients except sugar to a large pot
Mix 5 cups of plums, 1 tablespoon of orange zest, 6 tablespoons of pectin, and 1/4 cup of orange juice in a deep pot. If you want to reduce foaming add 1/2 teaspoon of butter.
Bring the mixture to a full rolling boil on medium-high heat. Stir constantly.
Add 6 cups of sugar and bring back to a full boil for 1 minute.
pour into hot jars
Pour or ladle the jam into clean, hot, half-pint-sized jars leaving ¼ inch headspace. Place the lids and rings on and process for 10 minutes in a boiling water bath at sea level or adjust for your elevation.
Remove the jars from the water bath. Allow them to sit on the counter for 24 hours then check if they sealed properly. The center will be indented down if they are. If not, place any unsealed jars in the refrigerator and use them right away.
Plum Orange Jam
Place the sealed jars in a cool, dry area and use them within the next 3 years. After that, the nutritional value begins to decrease.
