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 grated nutmeg
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.
