The jam must then be cooked over high heat in order to evaporate the water as quickly as possible and harness the power of the natural pectin. (Cooking time can vary, depending on a fruit’s water content, but once it’s at a rolling boil, expect to cook it for at least 40 to 50 minutes.
Can you over boil when making jam?
If you don’t boil it long enough the pectin network will not form properly. Boil it too long you risk not only losing the fresh flavour and colour of the jam but having a jam with the texture of set honey.
Do you stir jam when its boiling?
Do no stir jam once boiling, but use a wooden spoon to check it is not sticking on the base of the pan. Stirring lowers the temperature and delays setting point being reached. It is wasteful to remove scum too often. Do it at the beginning and at the end.
How do you know when jam is ready?
When the time is up, pull the dish out of the freezer and gently nudge the dollop of jam with the tip of your finger. If it has formed a skin on top that wrinkles a bit when pushed, it is done. If it is still quite liquid and your finger runs right through it, it’s not done yet.
Can I overcook my jam?

Do you put lids on jam when it’s hot?

Why is my jam so hard?
overcooking, adding too much pectin, using too little sugar or too much under-ripe fruit in recipes where purchased pectin is not added (i.e., long-boil or no-pectin added recipes). …
What is a hard boil for jam?
Jam making is much like candy making in that you’re applying enough heat to the fruit and sugar to raise the temperature over the boiling point of 212 degrees and alter the structure of the sugar. The jam reaches its ideal set point at 220 degrees, so keep careful watch.
How do you stop jam from burning?
Cooking the Jam
During the first phase, you only want to stir the jam enough to prevent scorching. The heat should be low if the sugar is still dry, or medium-high if the sugar is all dissolved already. If the sugar is still dry, you’ll need to stir continually until the juices run and the sugar melts.
How do you know if jam is cooked enough?
Use a candy thermometer to test the temperature of your jam. Take the temperature when the jam has reached a rolling, foamy boil. You are looking for a temperature of 220° F. The jam will set nicely at that temperature.
Should you put hot jam in fridge?
A: Opened home-canned jams and jellies should be kept in the refrigerator at 40°F or lower. “Regular” – or pectin-added, full-sugar – cooked jams and jellies are best stored for 1 month in the refrigerator after opening. They may last longer depending on the specific product and how it is used.
How can you tell if jam is done without a thermometer?
Spoon a little of the hot conserve onto the cold saucer. Return to the freezer for 2 minutes or until chilled. Touch the conserve. If it wrinkles and feels gel-like, it’s ready to bottle.
