How to Make Blueberry Jam (no pectin recipe) (2024)

FAQs

How do you get jam to set without pectin? ›

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.

If I want a thicker consistency, I use cornstarch since I always have it in my pantry. If using, dissolve the cornstarch in water first and make sure your blueberry mixture is simmering or you'll end up with clumps of cornstarch in your preserves.

Different fruits have varying levels of natural pectin, blueberries are low in pectin but apples are high. The fruits that are highest in pectin are apples, lemons, currants, grapes, sour cherries, cranberries, quince and lingonberries.

Over-ripe or damaged fruit is not ideal - the jam will not set well and is likely to deteriorate rapidly. The amount of sugar you need to make jam depends on the amount of pectin in your chosen fruit, but generally the fruit-to-sugar ratio for traditional jams is 1:1 (ie. 450g/1lb sugar to 450g/1lb fruit).

Lemons - Juice of one lemon and zest. Sugar - To help thicken and sweeten. I don't recommend substituting for a sugar alternative. Cornstarch - Optional, but works well as a thickener in place of pectin.

Strawberry jam with added pectin can be cooked in as little as ten minutes, preserving that fresh berry flavor and quality. Strawberry jam without added pectin needs to be cooked up to four times longer to reach the gel stage, resulting in a much sweeter, less fresh-tasting jam.

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. While you can simply reduce the jam to your liking, you can also add commercial pectin or chia seeds to the reducing jam to guarantee thickening.

With a simple lemon juice trick, your homemade jam will achieve your desired thick texture. Preparing jam is about capturing the sweet essence of the fruit while simultaneously cooking it down to the perfect syrupy consistency.

Sadly, sugar plays a huge role in set. If you cut the amount in the recipe and you don't compensate with a pectin designed for low sugar preserving, your jam may well be runny. Did you check for set while the jam was cooking? Any time a recipe gives you a cooking time, it's simply an approximation.

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.

How to fix runny jelly without pectin? ›

To remake cooked jam or jelly without added pectin, for each 1 L (4 cups) jam or jelly add 25 mL (2 tbsp) bottled lemon juice. Heat to boiling and boil jam or jelly hard 3 to 4 minutes, then test for signs of gelling.

The tartness of lemon provides a bright and zesty contrast to the sweetness of blueberries. Lemon can enhance the flavor of blueberries by adding a touch of acidity that brings out their natural sweetness. Both lemon and blueberry are versatile flavors that can be used in a variety of dishes, from sweet to savory.

5. Do Not Stir Once Mixture Is Boiling. Once your jam/marmalade it has reached a rapid rolling boil do not stir it. Stirring it will alter the temperature of the jam/marmalade meaning it will take longer to reach the setting point.

Adding too much sugar can result in an overly sweet jam that may be too firm or have a crystalline texture.

You will need approximately half the amount of pectin that is indicated by your recipe. Please be careful when adding pectin as too much will leave you with a set that is too solid and it is not possible to rectify this so always add less than you think is necessary and test the set and then add more if required.

The chia seeds soak up the juice and moisture from fruit purée and plump up, giving a thickening effect to the jam without using heat or added sugar or pectin. Think of it as a chia seed pudding made with fruit rather than milk.

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.

If the jam is still quite liquid then put the pan back on the heat, bring it back up to a rolling boil and cook for a couple more minutes before testing again. You may have to repeat this a few times before you find that your jam has set.

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).
