Blackberry Jam
Description
This Blackberry Jam recipe starts with fresh or wild blackberries combined with pectin and sugar. The berries can be crushed for a smoother texture or left whole for more fruit body. The mixture is brought to a rolling boil to activate the pectin, which helps the jam set.
After boiling with the sugar, the hot jam is ready to be jarred and either cooled for immediate use or processed with water bath canning for long-term storage. Foam may form during cooking and can be skimmed off for clarity but is optional.
The resulting jam is bright and sweet with the fresh taste of blackberries and a thick consistency that holds well. It can be used on bread, in desserts, or as a condiment. Proper sterilization of jars and follow-through with canning instructions are key for shelf stability.
Ingredients
- 2 quarts blackberry about 8 cups
- 7 cups granulated sugar
- 1.75 ounces pectin yellow box, SureJell brand, powdered
Instructions
- Measure out your ingredients. My blackberries were small wild ones, so I did not crush them first, but if you have larger berries or do not want discernible pieces of fruit in your jam, crush them first with a potato masher or a similar tool. You should yield 5 cups of crushed fruit from 8 cups fresh berries.
- If you are planning to water bath can this recipe, make sure you prepare all of your equipment and jars for canning ahead of time. I link to the method I like to use in the notes below.
- Add the berries and the pectin to a large heavy bottomed stock pot and stir to combine. Make sure your pot is relatively tall, as the mixture will expand and sputter when it comes to a boil.
- Bring the berries and pectin to a rolling boil. This means that the boiling does not go down when you stir it. You may notice foam forming on top, you can either ignore it or skim it off with a spoon and discard it.
- Once the mixture has come to a rolling boil, add the sugar and stir to combine everything well.
- Bring everything back up to a rolling boil, and pay careful attention to it once it gets to that point. Continue to boil for exactly one minute more, and then remove from the heat.
- Fill your jars (again, refer to the instructions linked below if you are planning to can this jam for longer term storage), cap them, and either proceed to water bath can them, or leave them to cool at room temperature until they are cool enough to transfer.
- If you did not water-bath can your jam, keep it in the fridge for up to 1 month, or the freezer for up to 1 year.
Notes
- Recipe yields just over 8 cups of jam, and nutrition information applies to 2 tablespoons serving size.
- For long-term storage, follow proper water bath canning procedures as outlined at Pickyourown.org to ensure safety and preservation.
- Using a tall, heavy-bottomed pot helps prevent boiling over, as the mixture expands and sputters when boiling.
