My Jam Didn't Set! What Should I Do? ›

Cook it again.

For every 4 cups of jam that needs to be remade, whisk together 1/4 cup sugar and 1 tablespoon powdered pectin. Pour the jam into a low, wide pan and add the sugar and pectin combo. Stir until the sugar and pectin has dissolved.

Adding an acid, such as lemon juice, is a good fix. And the easiest thing of all, a tablespoon of corn syrup. This is always my last resort, but it really works. The crystals have melted back into the jam and we're ready for toast.

Once the jam is done cooking, it may look a little thin, but just remember that it will thicken in the fridge as it cools. For a thicker version (good for fruits that are low in pectin, like blueberries, raspberries, strawberries, and peaches), add a tablespoon of pectin powder.

If this is the case, then heat your jar in boiling water to soften it, then pour it into a pan and reboil it, adding a little extra water. Then when it cools it will simply be a thick syrup, and shouldn't crystalise (Think how honey crystalises). Careful, if you cool it in your fridge it may still crystalize.

Yes, you can, but you need to be more careful to stir frequently so the sugar in the jam doesn't burn. If your jam didn't set, it might need more pectin which can be bought in some stores.

Lemon is crucial to balancing those sweet flavors, but it also helps the pectin to firm up the jam. It can be added at the start of the cooking process or towards the end, but what must be taken into account is that adding liquids to the jam mixture will inevitably require the jam to cook for longer.

- Overcooking is a problem that, it destroys the gelling capacity of the pectin. That can occur when the fruit is being heated to extract the juice, or while cooking the jelly itself. Likewise, undercooking produces problems because the jelly is not sufficiently concentrated.

If, on the other hand, the jam is rock solid, that means you've gone too far and cooked it too long. You can try adding a little water to thin it out, but bear in mind that after overcooking a jam, you can't really get those fresh fruit flavors back.

The secret ingredient to making jam without pectin is time. The fruit and sugar need plenty of time to cook and thicken. A long, slow boil drives the moisture out of the fruit, helping to preserve and thicken it at the same time. Fruit varies in water content as well, and some fruits may take longer to jam up.

Will jam set without pectin? ›

Making jam without pectin is easy, you just have to cook it longer. This recipe produces a very thick, rich tasting jam, but if you like your jam a bit looser, cook it 5 minutes less than the suggested cooking time.

Sometimes it can take 24-48 hours for the pectin to fully set. If you want to make sure your jam sets properly before you portion it into jars, spoon a small amount of hot jam on a plate, and place in the freezer for several minutes, just until chilled, but not frozen.

Longer cooking actually breaks down the pectin molecules. Eventually the evaporation of water makes jam thick but results in a gummy, sticky product, often with a darker color caused by the sugar caramelizing during the extended cooking time. Jam is best cooked rapidly, in small batches.

To remake cooked jelly or jam using liquid pectin for each 250 mL (1 cup) jelly or jam, measure and combine 45 mL (3 tbsp) sugar, 7 mL (11 /2 tsp) bottled lemon juice and 7 mL ( 11/2 tsp) liquid pectin. Bring jam or jelly to a boil stirring constantly. Add the sugar, lemon juice and pectin combination.

Stiff jams or jellies can be thinned with water or fruit juice. They may or may not form a gel again once they are re-heated, as over-cooking of pectin can reduce or destroy its ability to form the gel structure. You will need to experiment with how much liquid is needed to thin your jam or jelly.

Overcooked Jam: It's is harder to salvage overcooked jam. If the jam tastes scorched it's best just to throw it away and try again. If the jam isn't scorched but is too thick to use as jam, slowly heat it in the microwave with a little added water and use it as syrup.

Remove pot from heat and divide jam into sterilized jars, leaving 1/4-inch of space at the top. Seal and transfer jars into a boiling water bath. Make sure jars are covered with at least 1 inch of water; let sit for 5 minutes. Lift jars and let them cool in a draft-free place without touching, 8 hours to overnight.

If jam has separated, such as in the picture, simply stir it up when you open the jar of jam, and it will stay mixed and not separate again.

If, on the other hand, the jam is rock solid, that means you've gone too far and cooked it too long. You can try adding a little water to thin it out, but bear in mind that after overcooking a jam, you can't really get those fresh fruit flavors back.

Pectin Substitute

Cornstarch - Another plant-based thickening agent, cornstarch is a great substitute for pectin. Gelatin - For non-vegan menu items, you can substitute gelatin for pectin, but it will yield a different consistency.
