How To Make Mixed Berry Jam

  1. Add the fresh berries to a large saucepan along with the sugar. You will want to make sure that you have coated the berries in the sugar and let them sit for 15 minutes. Toss every 5 minutes as the sugar starts to dissolve into the fruit juice.
  2. Once ready, you can put the sauceplan on to a medium heat, and bring the berry mixture to a boul. Cover the pot and allow to simmer for around 15 minutes. You will notice the berrie start to burst. 
  3. Meanwhile, put a plate in the freezer. You will use this to test the conostency of your jam later on in the recipe. 
  4. Turn the heat up to medium-high heat and stir every few minutes until the juices start to thicken and you will notice a few air bubbles. Once the berry mixture has begun to thicken, reduce to a low heat and stir more often. This will stop the jam burning and from sticking to the pan. 
  5. Continue to cook for 30-35 minutes until most of the liquid has evaporated from the berries and it has completely borkwn down in texture. You will notice the mixture will also be at a slow, thick boil. You will notice smaller bubbles. Once you get to this point, add the fresh lemon juice.
  6. Mix together and then let the jam cook until you reach a thick consistency again. You will want it to be the same consostency as it was before you added the lemon juice. This should take around 5 minutes.
  7. At this point, the jam should be ready. To test take a small spoonful and place it on the small plate that you placed in the freezer earlier. Put in the refrigerator for a couple of minutes and then take it out and drag your finger through the jam. The jam mixture should hold its shape and not be runny. If it is runny then cook for another 5 minutes.
  8. Once the jam is ready, remove it from the heat and place it in a mason jar. Once cooled store in the refrigerator and use as you need to.
