Adventures in jam-making


I like to make jam. I’m not entirely sure why: after all, stores carry jam in all sorts of flavors for a lot less money and effort. (Of course, department stores carry sweaters in all sorts of styles and colors for a lot less money and effort, but I knit them anyway.) Unfortunately, most jam recipes I’ve found make jam for the masses. As a single person, even one still fond of peanut butter and jelly sandwiches, a recipe that promises to fill 8 half-pint jars at a minimum is off-putting. That would be 8 jars of the same flavor, and while I could probably work my way through that much strawberry preserves in a year or so, I want to play with other flavors. Also, I have zilch canning experience and an irrational conviction that if I try, I will kill myself with botulism poisoning. Terror aside, canning involves great quantities of steam and boiling water, neither of which makes a hot, humid summer afternoon any more endurable—and the hot, humid summer is when the fruits I love with are at their peak. I’ve tried making jam in my bread machine, which limited me to two recipes and was too hands-off to be any fun. When I finally found a small-scale recipe, I wilted from all the steam and stirring involved, and it still restricted me to about two variations with no suggestions as to how to substitute other fruits. Bleah.

This year, however, I found full instructions for freezer jam. No canning involved! As I looked into it further, I realized that you don’t cook the fruit either—so much for all that steam. And the crowning glory was that the recipe was scaled for anything from 1 to 6 half-pint containers and let you substitute in just about any fruit I wanted to work with. Okay, it involved buying one particular brand of instant pectin, but that was a small investment and worth it to see if it would make jam-making manageable. And so, armed with raspberries, blueberries, and strawberries, I set to work.

The process is dead simple. First, mash the fruit with a potato masher. The raspberries and strawberries behaved perfectly, as though they could imagine no higher destiny than to become jam. Blueberries, on the other hand, resist crushing. Tougher skins? And when they finally do burst, they spray everything in the area with juice. I’m hoping I didn’t just ruin a favorite T-shirt.

Next, mix the sugar and the pectin. The recipe swears that you can use certain sugar substitutes instead of sugar. I’m torn between thinking that that’s great for diabetics and anyone else who can’t or doesn’t want to eat a lot of sugar and thinking that that just makes it another odd chemical concoction. (Let’s not ask what was in the pectin that lets it work without cooking—I’m trying to convince myself that this was a fairly natural food.)

Finally, add the fruit to the sugar and pectin, stir for 3 minutes, pour into containers, and let sit for half an hour. Freeze or refrigerate.


Raspberry, blueberry, strawberry, strawberry, strawberry

Okay, as of this writing, it hadn’t jelled as much as commercial preserves. Maybe these will just have to be spread on toast or rolls or something, and not made into peanut butter and jelly sandwiches. I can live with that. And a few random observations:

  • 6 oz. (170g) of raspberries was just enough to make 8 oz. (237 ml) of jam. 6 oz. of blueberries wasn’t. Hmph.
  • My blueberry jam isn’t all that pleasant to look at (tastes fine!). Large commercial producers must be doing something to it to improve the appearance. I probably don’t want to know what that is.
  • That strawberry huller I bought 2 years ago was a wise purchase. Never mind that today was the first time I’ve used it.

  1. When my mother started making freezer jam instead of the cooked kind, I LOVED it. The strawberry jam…tastes exactly like fresh strawberries! Go figger. Enjoy yours!


    • I suspect it’s going to take some adjustment on my part. I like the idea of jam that tastes exactly like fresh strawberries (or raspberries or blueberries), but I’m really used to the kind that tastes like cooked fruit plus tons of sugar (and/or high fructose corn syrup).


  2. My friend Karen makes freezer jam every year with her sisters — they make a special trip back to their childhood home in Michigan to do it. Her strawberry jam is a much-coveted gift. Kudos to you for doing it in Minnesota!


    • Oh, if I had to travel anywhere to make jam, it would never get made. The day after Thanksgiving is Cookie Baking Day for my cousins, which has taught me that working in a foreign kitchen is discombobulating, and I’m a lot more used to baking than jam-making!
