Cook it again.

A runny batch happens even to the best home jammers. If, after waiting, you find the jam is still too loose for your liking, empty the jars back into a wide pot and cook again. Wash and sterilize the jars and try again.

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.

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 you like making gelatin for dessert, the box often recommends not adding certain kinds of fruit, including pineapple, kiwi, mango, ginger root, papaya, figs or guava. People have a hard time getting the gelatin to solidify when they add these fruits.

Your jelly should set in the fridge in around 4 hours. Note: you can add fruit or juice, but avoid fresh pineapple, kiwi or papaya as these fruits will stop your jelly from setting.

If jam comes out too stiff, it is often caused by overcooking fruit or the fruit spread having too much pectin. Pectin is naturally found in fruit and creates the gel and thickens jams and jellies.

Once the jam reaches a slow, thick boil, add lemon juice and continue to cook, stirring constantly until the jam returns to its earlier consistency, about another 5 minutes.

Alternatively, you could place the prepared jello in a sink/basin/bowl filled with ice cubes to speed up the process. At some point you will need to put this in the fridge. You may certainly put the mixture in the freezer but make certain to check frequently to avoid freezing.

Can you put warm jelly in the fridge to set? ›

If you are preparing the Jello with hot water, the water needs to cool down before you put it in the fridge. If you put it in too soon, you're putting the other food in the fridge at risk because it will no longer be properly cooled if you put in something hot.

For each quart of jam or jelly to be fixed, mix 1/4 cup sugar, 1/4 cup water or white grape juice, 2 tablespoons bottled lemon juice, and 4 teaspoons powdered pectin in a large pot. So, if you made a batch of jam and have 10 eight-ounce jars that didn't set, that would be an average batch (10 cups or 2.5 quarts).

If there isn't enough pectin in the fruit itself and you don't add extra pectin, the result is runny jelly or jam. Additionally, if the fruit is overripe, its pectin levels are lower. Added pectin comes in a couple of forms. You can find powdered pectin and liquid pectin at grocery stores and online.

If the jam is still liquid then we don't particularly recommend reboiling. It can be tried but there is a risk that the jam becomes over boiled, which also means that it will not set. The jam can also burn much more easily when reboiled. The thin jam can be repurposed as a sweet chilli sauce.

If you prefer a softer set, you can always use less pectin than called for in our recipes. We would suggest you experiment by using ¼ to ½ teaspoon less pectin than the recipe calls for, or perhaps up to a teaspoon less for recipes that call for 4 teaspoons of pectin. You would keep the calcium water amount the same.

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.

Remove the lid and check the jar-sealing surface for tiny nicks. If necessary, change the jar, add a new, properly prepared lid, and reprocess within 24 hours using the same processing time as recommended in the recipes..
