Ingredients for the Instant Pot Blueberry Jam

Blueberries- Organic blueberries are always the way to go if you can find them. If you can't find organic, use regular and make sure to wash them really well. I find the easiest way to wash them is to add them to a large bowl, add one tablespoon of white vinegar, and fill the bowl with water. Mix the blueberries around and then empty the water and rinse the berries one more time. You'll have perfectly clean berries! Frozen berries would work well here as well. You would not need to defrost them, simply put them in the Instant Pot frozen.

Lemon- The lemon juice cuts down on the sweetness from the berries. It gives the jam a little tang that is a compliments the sweetness of the berries perfectly.

Sugar- Sugar breaks down the berries and gives the sweetness to the jam. If you did not want to use sugar, honey would work as well. Don't use as much honey as you would sugar, cut it to ¾ cup of honey per 1 cup of sugar.

Cornstarch- Since we are not using pectin which would normally give your jam the gel like consistency, cornstarch will thicken the jam for us. Mix 2 tablespoons of jam with 2 tablespoons of water to thicken this jam.

Time to Make the Blueberry Jam!

Add the ingredients to the Instant Pot
Add the cleaned and washed blueberries, sugar, and lemon juice to the Instant Pot. Mix everything together and let it sit for 15 minutes to allow the berries and sugar to marry their flavors together.
Turn on the Instant Pot
Turn the Instant Pot on high pressure for 1 minute. The Instant Pot will take about 10 minutes to build the amount of pressure it needs, and then it will actually cook the berries for 1 minute.
Let it rest
Allow the Instant Pot to naturally release for 15 minutes. When you first open the lid, it will look like there is too much liquid, but do not worry! That is totally normal!
Add the cornstarch slurry
The water and cornstarch mixture is known as a "slurry". Mix 2 tablespoons of water with 2 tablespoons of cornstarch. Add that to the Instant Pot.
Sauté for 2 minutes
Press "sauté" on the Instant Pot and allow the jam to come to a rolling boil for 2 minutes. This process will help activate the cornstarch to thicken the jam.
Let it cool!
Allow the jam to cool for a few minutes before adding it to the jars. The jam will be very hot when it is done cooking. Enjoy!

Did you check out my 3 Ingredient Strawberry Jam? So good and the same technique! For this recipe, you could add another lemon at the end of the cooking process to really up that tangy flavor. You could also mix berries. Add some raspberries or blackberries to the Instant Pot to make a mixed berry jam.

Does this recipe double well?

Yes! Perfectly! I use a ratio of 2 pints to 1 cup of sugar. Use that ratio for when you are doubling or tripling this recipe. Add the jam to smaller Ball jars and give it out as gifts for teachers, mail carriers, or friends!
