When it comes to canning, blueberries were my gateway fruit (although they didn’t usher me through the doorway into the realm of canning preoccupation until I reached adulthood). Growing up, I’d often pick them with my family, but I always left the jam-making and canning to my mom, participating only when it came time to squish the berries into jammable shape with my fingers (there’s something so deeply satisfying about crushing those juicy little blue orbs into pulpy bits).
However, one fateful July day during the summer of 2007, my friend Seth and I decided to go blueberry picking and everything changed. That summer, I was in grad school and he was unemployed, so we both had free time on our hands. It was the first time I had gone berry picking without parents, a sibling or babysitting charges that needed to be entertained. We spent at least two hours out in the blueberry field, filling up our buckets and eating until our fingers were stained blue and our stomachs were ready to burst with fruit.
Later that day, when I was home alone with my berries, I did the thing that was innate. I called my mom for canning advice, ran across the street to the hardware store for some jars and pectin and made my first solo batch of jam. Thinking back on it now, it’s hard to imagine a time when I had so little canning experience, when I hovered anxiously over my filled jars, praying for them to seal (admittedly, there are times when I still check and recheck freshly processed jars, only able to relax when they ring out a ping of sealed success).
Since then, I have made at least 100 batches of jams, marmalades, fruit butters, chutneys and pickles. However, blueberry jam will always feel familiar, foundational and necessary in a way that no other fruit can match. Summer doesn’t feel complete without at least one blueberry picking trip and a batch of homemade blueberry jam cooling on the kitchen counter.
We’re heading into the end of blueberry picking season here in the mid-Atlantic region, but there are still to be found if you look (as a side note, if you’re interested in the history of cultivated blueberries, check out this interesting little article). You can also get them at the grocery store for relatively cheap prices, if you don’t have any u-pick farms in your area.
For those of you who want skip out on making your own batch of blueberry jam (or just need a little delicious inspiration), I have one half pint jar of this jam to give away. Leave a comment on this post in order to enter. I’ll close the giveaway on Friday (August 7th) at 5 p.m. eastern time. Good luck!
And on to the recipe…
Blueberry Jam
6 cups of smashed blueberries (you’ll need 8-10 cups of unsquashed berries to equal this amount)
6 cups sugar
1 lemon, zested and juiced
2 teaspoons cinnamon
1/2 teaspoon nutmeg, grated
1 box (two packets) liquid pectin
Fill your canning pot with water and begin to bring it to temperature. Wash your jars and rings in warm soapy water and set aside. Put your lids in a small pot of water and heat (but do not boil) in order to soften the sealing compound.
Add smashed blueberries and sugar to a large, non-reactive pot. Bring to a boil and add cinnamon, nutmeg, lemon zest and juice and let jam continue to cook for about fifteen minutes. Add pectin and bring to a rolling boil for a full five minutes.
Turn off the heat under the jam and fill jars. Wipe rims and apply lids. Screw on the bands and lower into the water. Process in the hot water bath 10 minutes. When time is up, remove from water and cool on the counter. When the jars are cooled, check the seal by pressing on the top of the jar. If there’s no movement, the jar has sealed. Store up to one year in a cool, dark place.
Eat atop fresh scones or biscuits for maximum enjoyment.

For me, it’s strawberry jam and raspberry jam. I prefer the freezer jam for them though, because I find it just has a fresher, truer flavour. Blueberry picking is starting very soon up here in northern Canada, and I love canning blueberry syrup for pancakes (my recipe says to strain the berries out before canning, but I like to leave them in.)

I love blueberries. Last year I made my weight in blueberry butter and syrup. It was my first year canning, so I didn’t know how much to can. Well come February or March, no canning food left. This year doubling or tripling things. On all my days off canning is commenced in my household. I’m enjoying every minute of it. I’m going to make blueberry jam this coming weekend. I made sweet cherry jam yesterday. Wonderful is not the word. First time in Jam Land for myself. I made alot of freezer jam last year and some this year. I want to make more regular jam. Everyone enjoy the blueberries while they are still here. Luckly I found a 10 lb. box at the farmers market for $25.00. Great deal!

I have a question. I noticed you have used liquid pectin in several of your jams. Any reason why? Does it make better setting? Let me know!
Amelia, I use liquid pectin because it gives the jam a more natural, soft set than the powdered stuff. I don’t like the rigid set that jam takes on when you use powdered pectin. However, I’ve been told that the liquid pectin is harder to find, so if you can’t find it, feel free to substitute in the powdered pectin. -Marisa

Blueberries are such a good first canning experience because you don’t even have to chop them. What size are those squatty jars and where did you get them?
Mama Urchin, it’s true about about blueberries being a good first experience. I love that the prep necessary to make blueberry jam is so little! Those squatty jars are the Ball’s Collection Elite and the ones pictured are pints. They also make some very cute half pints that I like. The one problem with these jars is that they’re a bit more expensive than the standard jars, so I’m careful to only use them when I’m making a small batch of something that I’m going to give away. -Marisa

I love blueberries. Sadly, the only farm within 35 miles where you could pick them was sold to a developer for houses. However, the supermarket has had some good ones at pretty reasonable prices, maybe not for jam making but at least for munching. I like to add them to cereal, to biscuits, to yoghurt, to my hand for fresh munching.

Blueberry jam was my first too. I think I waaaay overcooked it because I was so nervous about it gelling.

I would have never thought of that combination but it works!

Hello,
I really appreciate the calm, level headed advice and experience you give at your website.
This week I am going to try putting up blueberry jam. I live in a small apartment with what I laughingly call Barbie’s Dream Kitchen: a small kitchen with small appliances. A regular sized canner will not fit on top of my stove. If I use a small stockpot and stack the jars will it derail the water bath process? Must the jars be processed in a single layer?
I’m am in the process of getting rid of all my plastic ware for storage and am slowly replacing it with glass. I’ve begun intentionally buying things in glass jars at the supermarket: first I use the contents then I use the jars for storage later.
Love the site,
TonyB

I’ve been making several batches of no sugar added blueberry jam over the past couple weeks & have sold out every time I make it. I still have another batch I have to make tomorrow (maybe the last for the season) & to be honest I’m not looking forward to it. Everytime I’ve made it, when it comes to a rolling boil it splatters all over & I have to hurry to wipe it up before it stains my counters. I try to keep a lid on it but them I run the risk of the bottom getting thick/burning if I don’t stir it often enough & then when I do it jumps out of the pot & “bites” my hands, then I end up with little burn blisters. Anyone else have this problem?? I’ve also been making several other types of jams (watermelon, honeydew, cantaloupe)& none of them boil out of the pot as violently as the blueberry.

@Heather: It sounds like you’re cooking at too high a temperature or your pot isn’t big enough. This recipe bubbled for me but not splattering onto the stovetop. I use a splatter guard (one of the ones designed for deep fryers) because you can still wedge a spoon underneath to stir.
I made this yesterday and it’s delicious blueberry goodness. The yield was 10(!) half pint jars for me.
