Made with sugar and fresh lemon juice, Crockpot Express Blueberry Jam is the perfect combination of sweet and tart flavors!
Here’s how easy it is to make this Crockpot Express Blueberry Jam: I made it in my cabin while at summer camp with my son. I have to say, this is probably the most unusual place I’ve ever done any cooking. 🙂
I knew there would be a lot of down time for me while he was participating in different camp activities like archery tag (don’t ask) and swimming in the lake. So I packed up my CPE and a box of supplies so I could do some recipe testing. I even brought my camera and took pictures right in my cabin!
This blueberry jam was done in just a few minutes and it’s so fresh and sweet. Blueberries and lemon marry well together-the jam is tart and sweet at the same time. I like to spread it on a piece of bread and eat it like dessert. It’s also delicious on pancakes and waffles! Skip the syrup completely and spread some blueberry jam or even Crockpot Express Strawberry Jam on top. Yum!
Now, when you first read this recipe, you may think there’s nowhere near enough to liquid to get the pot to come to pressure. Trust me, I had my fingers crossed a few times, but it works beautifully! Once the pot starts to heat up, the blueberries break down and release their juice quickly. You don’t even need to mash the berries up afterwards like you might with strawberries.
To help keep the sugar from sticking to bottom of the pot, be sure to add the berries first. Then sprinkle the sugar over the top and squeeze the lemon juice all over. Don’t stir. This will keep the sugar from clumping up on the bottom. You’ll be amazed when you open the pot and see all the liquid in there.
How much you cook down the liquid is up to you. I let mine simmer for 3 minutes and then added the slurry to let it do its work. Almost immediately, the jam thickens up. I didn’t more than a minute more of simmering to reach a nice thick jam consistency.
For storage, I like to use canning jars with plastic reusable lids. It’s much cheaper than buying rings and sealing lids, which you don’t need since this isn’t for canning and shelf storage. This Crockpot Express Blueberry Jam recipe will fit in one quart jar, or you can store it in several small jars.
