BLACKBERRY JAM

Steps:

• (If you are planning to can the jam, prepare waterbath and sterilize jars).
• Clean berries just before using. Add the blackberries and lemon juice to an extra-large saucepan. Mash with a potato masher and simmer for a few minutes, to break down the fruit.
• (Optional, but recommended:) Use a food mill, or press mixture through a fine mesh strainer, into a bowl, to remove seeds.
• Measure out 4 cups of berry juice and add to an extra-large heavy bottomed stock pot. Add 2-3 spoonfuls of the leftover seeds for blackberry "jam". (Jelly uses the juice only).
• Add sugar and stir to combine. Turn burner to medium low, stirring occasionally, cooking for several minutes until sugar has dissolved.
• Increase the heat to medium high, and cook, stirring constantly, until the mixture comes to a full boil (a rolling boil that can't be stirred down).
• Add the pouch of pectin, stirring continuously, and allow to return to a full boil. Set a timer for 1 minute, stirring continuously, and remove from the heat after 1 minute.
• Pour jam into prepared jars and seal with lids.
• For Freezer Blackberry Jam: Allow the jam to cool at room temperature for 24 hours, then store in the fridge for up to 1 month, or the freezer for up to 1 year.
• To Can: Process in a boiling water bath for 10 minutes (or longer if at high altitude*). Allow to rest on your counter for 24 hours, to ensure the jars settle and seal properly. Check seals, and store jam in a cool, dry place for up to one year.

BLACKBERRY JAM

Steps:

• The night before you make your jam, layer the blackberries and sugar together in a very large bowl, then cover and set aside at room temperature. This helps the sugar to start dissolving so you don't run the risk of over-cooking the fruit when you actually begin to make the jam. The next morning, give everything a quick stir, then set aside again until you are ready to start cooking.
• Before you start, put a small saucer in the freezer. Take a preserving pan or a large, wide-based pan (the wider and more open the pan, the faster the jam will be ready, so a preserving pan is really ideal) and tip the berries in, scraping out all the juices and any undissolved sugar. Stir in the lemon juice, then collect all the pips and secure them inside a tea-leaf strainer or piece of muslin before adding them to the pan (cooking the pips along with the fruit extracts the pectin they contain, helping your jam to set).
• Start the blackberries over a low heat until all the sugar is completely dissolved, then bring to the boil and simmer for 5 mins. Turn off the heat and spoon a little hot syrupy jam onto the chilled saucer. Once it's cool, push it with your finger. If it wrinkles a little, it's ready and has reached setting point. If it's too runny to wrinkle, return the pan to the heat and boil in 2 or 3-minute stages, removing the pan from the heat each time you do the saucer check, until the jam wrinkles.
• Skim off any excess scum, then stir in the knob of butter, if you want - this will help to dissolve any remaining scum. Leave the jam for 15 mins before ladling into sterilised jars - this allows the fruit to settle so it doesn't sink to the bottom. The jam will keep in a cool, dark place for at least 6 months. Refrigerate jars once opened.

OLD-FASHIONED WILD BLACKBERRY JAM

Steps:

• Rinse the blackberries, then add them to a large pan together with the sugar and the lemon juice.
• Leave to simmer on a low to medium heat until the liquid released is nearly absorbed, and the jam is thick enough to be poured into jars, depending on the heat that could take up to 2 hours.
• The jam will thicken further when it cools down.
• Rinse the jars, and place them in the oven at 180 degrees Celsius (350 Fahrenheit) for 10 minutes to sterilise.
• Pour the hot jam into the hot jars, making sure you do not fill the jars to the brim, but there is about half an inch of headspace.
• Tighten the lids well, then place the jars upside down and leave to cool completely.
• If the fourth jar is not quite full, it can be stored in the fridge and consumed within 3-4 weeks.
• Otherwise, the jars can be stored in a cool place, and the jam should last for 1-2 years.

BLACKBERRY JAM

Steps:

• Mash blackberries in a saucepan with a potato masher. Stir in sugar until juices form; place about 1 tablespoon blackberry juice in a small bowl and stir in cornstarch. Pour cornstarch mixture into saucepan.
• Bring berries to a boil, stirring often, until jam is thickened, about 15 minutes. Stir in cinnamon and allspice. Remove from heat and allow to cool. Transfer jam to a bowl, cover, and refrigerate until chilled. Stir in lemon juice.

BLACKBERRY JAM

Steps:

• Place the berries in a large stainless steel or enamel saucepan. Bring to a full boil over high heat, mashing the berries with a potato masher as they cook. Add the lemon juice and boil hard for 1 minute, stirring and mashing constantly.
• Add the sugar and return the mixture to a boil. Cook, stirring constantly, until it begins to look syrupy and thickens slightly, about 5 minutes. Remove from the heat and test for doneness: a candy thermometer should register 220 degrees F and the mixture should coat the back of a spoon. Run a finger--or a clean object about the width of a finger--through the coat of jam. If the jam does not run and fill the gap, it is done. Otherwise, return the pan to the heat for another 1 to 2 minutes and test again. Be careful not to let the mixture get too thick--it will thicken as it cools.
• When the jam is done, transfer it to a heatproof jar and cool to room temperature, about 2 hours. Cover with a tight-fitting lid and refrigerate. The jam will keep for up to 2 weeks.

APPLE & BLACKBERRY JAM

Steps:

• Put two small plates in the freezer ready to test the set of the jam. Put the apples in a heavy pan or preserving pan with the lemon juice and 250ml water. Bring up to the boil, then simmer for 5-8 mins until soft.
• Add the blackberries and sugar and stir to combine. Stir over a low heat until the sugar his dissolved, then turn the heat up to medium and simmer for 30-35 mins until the jam is at setting stage.
• To test the jam, take one of the plates out of the freezer and place a little bit of jam on it, if it sets and when you run your finger over it and it wrinkles, it means it's ready.
• Using a funnel, transfer the jam to a sterilised jar. Make sure you seal the lids once it's cold. Will keep in the fridge for six months in a sealed, sterilised jar.
