MAKE JAM WITH FRESH OR FROZEN BERRIES

Making homemade Blueberry Jam is a rewarding and delicious experience. Nothing tastes quite as good as making your own jam! I have been sharing all of my jam recipes with you lately and if you’ve noticed one theme, it’s that I use flavored Jell-O as my secret weapon. It adds sweetness and flavor. Because, let’s be honest, sometimes berries just aren’t always as berry tasting as we’d like them to be, right? With fresh or frozen blueberries, you can make a delicious homemade jam to enjoy all year round. Plus, they’re great to give as gifts too!

FREQUENTLY ASKED QUESTIONS:

How many fresh blueberries should I use instead of frozen?

You’ll need about 4 cups of fresh blueberries.

Do I have to use the Jell-O?

It’s my secret ingredient. You don’t need to add any additional pectin and it really enhances the blueberry flavor of this jam. But if you don’t want to use it, you can use a 3-ounce package of Certo liquid fruit pectin. You will also need to increase the sugar to 4 cups of sugar instead of 3 1/2 because the Jell-O comes with added sugar).

What can I serve this on?

You can serve this homemade jam on just about anything. Biscuits are the obvious choice, but spread some of this on my homemade English muffin bread and see how incredible that is!

Why do you like to use frozen berries?

A lot of people don’t realize this but frozen fruits and vegetables are picked and frozen right at the peak of freshness. So you can almost guarantee you are going to get the best version of that fruit. You also can rely on frozen fruit to be consistent in flavor whereas fresh can vary depending on when or where it was purchased and whether its under ripe or over ripe.

Does this have to be a chunky jam?

I like this as a chunky jam, but if you want a smoother one, you can use an immersion blender to smooth it out.

What size jars do I need to use?

I use these 11 ounce jars (you’d get just over 4 jars) or you can use these 8 ounce jelly jars and you would get about 6 jars.

How long does homemade Blueberry Jam last?

Homemade jam should be stored in the refrigerator for about a month (two at the most).

Do I have to scoop the foam off the top?

You don’t actually have to do this but I think it makes for a prettier, clearer jam. It doesn’t effect the taste really. It only takes a few minutes and I think it’s worth it.

I don’t like the seeds, can I remove them?

To me, blueberry seeds are so minuscule that you don’t really feel them in there but some folks swear they do, or for whatever reason, just don’t want or like them in there. You will have to do an extra step of straining the seeds out through a mesh strainer. You’ll probably need to help push it through as well because it will be thick. I never do this as we all enjoy the whole fruit in there and there are a lot of health benefits to leaving the seeds in.

Can I preserve this jam?

Yes. You can use a water bath canning procedure. I recommend trying these directions here. 

Can I freeze this?

You bet! In fact, you can freeze it for up to a year!

INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)

  • frozen blueberries – as I have stated in the post, you can use fresh berries (quantities given above). The berries do not need to be thawed first.
  • sugar – it may seem like a lot of sugar but it really is perfectly balanced. You can certainly use less sugar if you prefer. I have not tried this with any sugar substitutes.
  • berry blue Jell-O – This is really the only Jell-O flavor that works with this jam. See my FAQ above on how to make this without Jell-O.
  • fresh lemon juice – this brightens the flavor of the berries. It’s not absolutely necessary but I think it really helps to bring out their flavor. I only use fresh, not the bottled stuff.

HOW TO MAKE BLUEBERRY JAM

Wash and dry jars with lids. In a 3.5 quart pot, over medium-high heat, add frozen blueberries, sugar, berry blue Jell-O and lemon juice. Stirring regularly.

Once sugar has dissolved (this takes anywhere from 8-10 minutes), take a potato masher and begin mashing all the berries until mostly smooth. Allow the mixture to come to a gentle boil then turn down to a simmer for about 5-6 minutes.

As it simmers, you’ll notice a light pink foam gathering at the top. Skim off any “foam” from the top of the simmering jam using a spoon.

    I did a search for raspberry jam made with jello,and this came up. I added the 3 1/2 cups of sugar. It set up quickly. Decided to do a second batch. This one, I added two cups of water, two jalapeños, then blended with a stick blender. So nice to see someone besides myself who loves to experiment. The jam has a wonder, intense flavor. My husband and I ate the leftovers from the first batch on toast for out lunch.
