I came away from our first hands-on lab with a new-found appreciation for homemade jams and jellies, the topic of our next class in the Master Food Preserver Program. Timed to coincide with strawberry season, flats of fragrantly ripe strawberries from Fairwinds Farm in Bowdoinham, ME, awaited us for processing.

We began the class by examining a sample jar of strawberry jam (above) made by our teacher, Kathy Savoie. We noted that it lacked headspace, and that the fruit fiber had separated from the juice, both problems common to homemade jams, particularly those made with strawberries. To gel properly, jams and jellies need to contain the right combination of fruit, pectin, sugar and acid. Even so, fruit can be fickle and have differing levels of naturally occurring pectin that may affect the end results.

If you’ve ever looked at a jam or jelly recipe, the amount of sugar required can be off-putting. In a nod to modern tastes, we tested and compared different ways of making strawberry jams and jelly using low/no sugar pectins, including one method using no added pectin.


The first group made strawberry-rhubarb jam, sweetened with honey and using Pomona’s Universal Pectin. Since Pomona’s doesn’t need sugar to gel, jams and jellies can be made with less or no sugar, or an alternative sweetener.
Pomona Universal Pectin:
• Pros: Little or no sugar needed; may use alternative sweetener; allows doubling of batch; indefinite shelf life.
• Cons: Tendency to separate (need to stir before eating); doesn’t hold color.
• Contains: Citrus pectin, calcium (monocalcium phosphate).


The second group made low-sugar strawberry jelly with Sure-Jell (pink box), another pectin that sets with little or no sugar. After washing, crushing and simmering the strawberries, the juice was strained off with a jelly bag. Instead of sugar, the jelly was sweetened with fruit juice, which made for a more subtle tasting jelly.
Sure-Jell:
• Pros: Little or no sugar needed; may use alternative sweetener.
• Cons: Shorter shelf life, advise replacing yearly.
• Contains: Dextrose, fruit pectin, fumaric acid (for tartness), sodium citrate.


The third group was assigned making no/low sugar strawberry jam using Ball’s No-Sugar Needed Fruit Pectin (green box). The process was the same as when using regular pectin, but allowed us to use honey as a sweetener, though we could have also used fruit juice.
Ball’s No-Sugar Needed Fruit Pectin:
• Pros: Little or no sugar needed; may use alternative sweetener.
• Cons: Shorter shelf life, advise replacing yearly.
• Contains: Dextrose, fruit pectin, citric acid (assists gel), calcium ascorbate (retains color).


The last group made a classic strawberry jam with no added pectin. The recipe from So Easy to Preserve required 6 cups of sugar to 2 quarts of crushed strawberries, and was rapidly boiled until thick, about 40 minutes, before canning.
No added pectin:
• Pros: No pectin necessary; even dispersal and consistency; true strawberry color.
• Cons: Large amounts of sugar; tendency to scorch while cooking.

The lineup for comparison (left to right): low sugar strawberry jelly (Sure-Jell), low sugar strawberry jam (Ball’s), strawberry jam (no added pectin), and low sugar strawberry rhubarb jam (Pomona’s).
What I learned: Read the recipe or package directions; follow the recipe or package directions; make one batch at a time; don’t reduce the amount of sugar or make a substitute unless the pectin is designed for it.

It’s a matter of individual taste which method you end up choosing, each has its own set of trade-offs. This recipe for Small Batch Fresh Strawberry Jam is a good alternative. For larger batches, my personal preference is Pomona’s Universal Pectin; I’m willing to overlook its drawbacks in terms of consistency and color for something with a more natural set. Another choice would be to use homemade pectin.
