A Year Of No Sugar: Post 81

November 9, 2011 § 5 Comments

Among my many experiments this year I tried making a No-Sugar Grape Jelly. I had my work cut out for me: if you’ve never made jelly or jam then you might be astounded to know exactly how much sugar actually goes in the average batch. It’s not uncommon at all for a batch of, say, blueberry jam to call for seven cups of sugar. Yes. Seven. This works out roughly to a cup of sugar per pint jar. Think of that the next time you have toast.

Like baking, jam isn’t improvisable. Unlike making a stew or omelette where you can just throw in what you’ve got and get something edible at the end, jam is really a science. In order to get jam or jelly to “set up” correctly, ie: get that gelatinous, not-liquid-not-solid consistency, you have to have an appropriate amount of pectin, which naturally occurs in fruit, and more so in unripe fruit. In the olden days jam must’ve truly been an art form, figuring out what percentage of ripe to unripe fruit to use, testing with a cold spoon to see if after cooking the jam had “set” properly, before beginning the long, hot procedure of “processing” your sterile jars filled with jam to make them seal correctly for storage.

These days, most jelly and jam makers add powdered pectin to the cooking fruit, which ensures that your jam will set up like a golden retriever every time. In recent years, I’ve made many batches of delicious jam in just this way. So I wondered: what if I made a jelly that followed all the instructions, but substituted dextrose for sugar? Would it work?

This was going to be a lonely journey, however. If you a modern canner, then you know that the literature available about canning today is not for the faint of heart. “WHATEVER YOU DO” they all read in the most alarming font they could find, “DO NOT, REPEAT DO NOT TAMPER WITH THESE RECIPES IN ANY WAY OR YOU AND EVERYONE YOU’VE EVER LOVED WILL MOST ASSUREDLY DIE FROM SOME TERRIBLE FLESH-EATING BACTERIA!!!!” I have at least four books with canning recipes and they all say virtually the same thing: no improvisation allowed. NONE. Story’s over, go to bed.

Meanwhile, if you talk to the old-timers, the ones who canned decades ago with things like rubber seals and wax, you get an entirely different story. They all say the same thing: “Oh, it’s fine. Don’t worry. Jam is incredibly hard to spoil! And even if it does mold on the top a bit, you just scrape that bit off and eat it anyway.” !!!! Now, I probably wouldn’t go so far as to eat mold-encrusted jam, but wasn’t there a happy medium we could arrive at here? Was a homemade “no sugar” jam possible?

At the end of September the concord grape vines in my backyard were sagging with fruit and I decided I would try my experiment on these. This adds an extra step- I usually prefer jam with nice big chunks of fruit and skin throughout, but Concord grapes have to be made into jelly, not jam, because of the seeds and tough skins which must be removed. After cooking and straining the grapes through cheesecloth, I began to boil the sweet juice.

Now right here I realized I already had a problem. Juice? I stopped right in the middle of my steaming, juice-slopped kitchen, with the sudden realization. We haven’t had juice since January 1, even as a sweetener, where it crops up often at the health food store. The family rule is: fruit must have corresponding fiber attached. Period. Huh. Why hadn’t I thought of this before? What should I do? Well, I was dying to know if my experiment would work, and, I rationalized, if it did, it could be extrapolated to jams which would include the skins and pulp. But today grapes were what I had to work with. Onward.

Now, every box of pectin from the supermarket comes with a long list of instructions for most types of jam or jelly you might want to make, so I dutifully followed the grape instructions to the letter: After discarding the seeds, skins and pulp, I brought 5 ½ cups of my fresh concord grape juice to a boil in a large open pot on the stove. This, by the way, is the very best part of making jam or jelly- the incredible fresh cooking-fruit smell that permeates every corner of your home. Potpourri has nothing on this. If I were to invent a perfume I think it might be “Concord Grape #5,” or possibly “L’eau de Peach.”

At this part of the procedure, with the boiling fruit in one pot and empty glass jars sterilizing surgically in another, I always feel like I’m engaged in some wonderful alchemical process that will transform some delicious but humble fruit into pure edible magic. They’re so beautiful, jars of jam in translucent hues sitting glinting on our shelves, waiting to remind us in the depths of a Vermont winter what the tastes of summer were. In the case of our concord grapes it’s even better because they’re free: the things grow like weeds in our backyard, no matter how badly we treat them, but due to the seeds and skins they aren’t much of a tasty snack. Without the jelly, this wonderful taste would pretty much go to waste, enjoyed by our backyard birds alone.

So I followed the recipe. After boiling the intense, incredibly purple juice for ten minutes I added ¼ cup of dextrose (instead of the called-for sugar) to a bowl containing the pectin powder and stirred this into the pot. (This is an extra step which you do with what I buy, which is “Low-Sugar Pectin”: it enables you to use less sugar in your jam, say five cups of sugar instead of seven. Seriously.) Brought to a boil, I then added the rest of the dextrose- 3 ½ more cups. Boiled exactly one minute, and then removed from heat and I began ladling into sterilized jars.

Actually, I cooked it a little longer than one minute, trying to ascertain whether the set-up would really occur using the dextrose. It looked right- gelatinous and jelly-ish. But I’d always relied on pectin to do this part for me… The boiling purple lava was ladled into the jars, hot lids screwed on “finger-tip tight” and into the bigger pot they went for the final sterilization. The filled jars boiled underwater for the requisite five minutes before being pulled out with jar tongs to cool on a dishtowel.

The sad news is that my jelly didn’t set. We proceeded to do what jelly and jam makers have done with failed jelly and jam since time immemorial: we had a lovely sauce. The kids liked it on crackers and on toast. It was sweet…ish. Unlike any jelly I’d had or made before, it truly tasted of the unalloyed grapes. Now, if only the set could be improved…

My research continued. I was determined to figure out what went wrong- and I began to learn a lot of disturbing things. For one, guess what store-bought low-sugar pectin has in it? Now, if you can’t guess by now I’m going to be very disappointed. Yes! SUGAR. That’s right: the low-sugar pectin- “for use with less sugar!” has sugar in it. How ironic. How totally predictable.

Turns out, there is a pectin that you can order or find at the health food store that contains NO sugar, called Pomona’s Universal Pectin. (Instead of being activated by sugar, it is instead activated by calcium.) Even Pomona’s, however, doesn’t list recipes omitting sugar- sugar, honey, artificial sweetener and juice concentrate are all listed, but no sign of the No Added Sugar recipe I’ve been searching for.

(Incidentally, I realized, it helps not to call it Jelly or Jam. “Fruit Spread” seems to be the term of choice for No Sugar variants of this process. Recipes are available online for Fruit Spread which look promising, although the ones I found don’t allow for canning. Rather, they produce a batch that lives in the refrigerator or freezer, which is functional if not quite so beautiful. That might be worth a try.)

But still, I wondered, was there some magical reason sugar was absolutely needed in canned jam and jelly? Was I going to kill my family with my homemade grape “sauce”? Why was the answer so strangely, incredibly elusive? Fortunately a few credible resources do exist online to help those of us who wish to cross over to the dark side of messing with/ understanding our canning recipes: both Oregon State and Colorado State Universities have good Extension websites which finally helped explain what I wanted to know: that, yes, sugar acts not only as a flavoring agent, but also acts as a preservative. And it activates the pectin to activate the “set.”

Silly me, this meant I was adding pectin to my grapes, without the required mountain-load of sugar present to activate it. Did putting it my jelly do virtually nothing? Or would dextrose do the same but just require different amounts? Also, tragically, my grape “sauce” would likely have a shorter shelf-life than the average estimate of a year for canned items. I could live with that.

Wow. You’d think they’d cover all this in Canning and Preserving for Dummies, right? But they don’t. Just shut up and follow the recipe, people. And anyway, what kind of crazy person would ever want to make grape jelly without sugar?

Where Am I?
