Blackberry Jam
Description
To prepare this Blackberry Jam, fresh or frozen blackberries are washed and drained before being processed through a food mill that removes seeds and produces a smooth fruit puree. This seedless puree is combined with granulated sugar and lemon juice in a large pot. The mixture is heated to a rolling boil and stirred frequently to prevent scorching.
The jam is cooked until reaching 220°F, a temperature that indicates the pectin and sugar have combined sufficiently to create gel-like consistency upon cooling. The hot jam is then ladled into sterilized jars, leaving a 1/4 inch of headspace. After sealing, the jars can be processed in a water bath canner for five minutes to ensure shelf stability or stored in the refrigerator if not sealed.
The finished jam has a rich blackberry flavor with balanced sweetness from the sugar and a slight tang from the lemon juice, making it ideal for spreading on breads, toast, or using in desserts. Proper sterilization and sealing allow for up to one year of storage in a cool, dark place.
Ingredients
- 9 cups blackberry fresh or frozen
- 5 cups granulated sugar

Instructions
- Wash and drain the blackberries. Run them through a food mill to remove the seeds. Reserve the blackberry puree (you should have about 5 cups) and discard the seeds.Place the blackberry puree in a large pot and add the sugar and lemon juice.Bring the mixture to a boil, stirring regularly, until the jam reaches 220 degrees F. I use an instant read thermometer.Ladle the jam into sterilized jars leaving 1/4 inch headspace and wipe the rims clean before sealing.If you're not sealing the jars the jam will keep in the fridge for several months.If you're using the water bath canning method process the jars for 5 minutes. Carefully remove the jars, let them sit undisturbed for 24 hours, then store in a dark cool place. Jam will keep for up to a year. Makes about 6 half pint jars.
