“Bluebarb” Jam

When I saw that this month’s Tigress Can Jam assignment was either rhubarb or asparagus, I had to laugh, since I had just canned rosemary-infused rhubarb jelly for last month’s assignment. I do love rhubarb though, so I decided to find a new and different way to use rhubarb for this month’s challenge. Fortunately for me, after I tweeted about it, Renee came to my rescue with several interesting rhubarb recipes. One of them was this recipe for “bluebarb” jam, which I was totally drooling over, and which comes from the Complete Book of Small-Batch Preserving. Definitely perfect for spring! Give this one a try (and check out my canning tips if you need any help)!

  • 3 1/2 cups chopped fresh or frozen rhubarb
  • 1/2 cup water
  • 2 1/4 cups coarsely chopped fresh or frozen blueberries
  • 1 Tbsp lemon juice
  • 1 package (1.75 oz) powdered pectin
  • 5 1/2 cups sugar

Place the rhubarb in a large pot with the water. Bring to a boil over high heat. Cover and reduce the heat to low and simmer for about 5 minutes.

Add in the blueberries, lemon juice, and pectin, and mix well. Bring to a boil over high heat, stirring constantly. Add in the sugar, then return to a full boil and boil hard for one minute, stirring constantly.

When ready to can, prepare your supplies. Bring the temperature of the glass jars up by processing them in hot water for several minutes. Heat a few cups of water in a small saucepan for the lids.

Remove the rhubarb mixture from heat. You can pour it into the jars  now, or process in your food processor like I did if you want the mixture to be a little smoother. When the jars are ready, fill them with the jam to 1/4″ headspace and place the lids and bands on top, screwing on the bands just to fingertip-tight. Place the full jars back into the boiling water and boil 10 minutes. Remove from the water and place the jars on a towel, and let the jars cool. The seals should suck down (you’ll hear a popping noise as they do). Makes 6 eight-ounce jars.

    what a gorgeous color this produces. what’s the flavor profile? does the blueberry overwhelm the rhubarb? i had a problem with that in my rhubarb concoction. great job!

    This jam sounds so yummy. I was tweeting with Gloria (from “The Laundry”) the other day about rhubarb jams and she mentioned a similar recipe to me: rhubarb blueberry and lime jam. I still have (raw-packed) canned blueberries from last year and some fresh rhubarb left, so when I get home from work today, I’ll make this jam!

    This was my first try @ any jam ever never and it was good! Since I am such a newbie though @ canning, I was wondering about something. Mine kind of forms a coating on the spoon when I take it out. Almost like a “skin”. Did I do something wrong? It tastes great but I was wondering if you had a similar experience or could tell me what I did??? Thanks for any guidance. Did you enjoy yours?

    Tammy – So glad you enjoyed it! I love it too. Do you mean that the jam formed a coating on your spoon while you were cooking it? It just sounds like your jam is beginning to set from the pectin.

    The Cosmic Cowgirl – I thought the flavor combination was perfect! But, you can always use more rhubarb and less blueberry if you prefer a stronger rhubarb taste. Enjoy!

    Well yes, when I was cooking it – but it still does it like when I get it out to put in my yogurt – it’s not as bad, but still sticky like.

    I made a lower sugar version of this yesterday and I thought I died and went to heaven. Instead of water I cooked the rhubarb in a 12 oz can of frozen apple juice. I only needed to add about 1/2 cup of splenda and the special low-sugar surejel. It was marvelous. I went out and picked more rhubarb this morning and am making another batch to give as gifts.

    Tennessee Tess – It sounds delicious! However, please note that sugar is an important preservative in water bath canning, and since you did not use the sugar in the recipe, the jam you made will definitely have a shorter shelf life than traditionally sweetened preserves. Fruit juice sweetened jams last about six months before the begin to discolor or mold, so please make sure to label them appropriately!

    OMG. Just made a double batch. Used wild MN blueberries I picked and rhubarb from tue garden. It’s AMAZING! Thanks for sharing!
