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.

Steps:

• Prepare the boiling water canner before starting to cook your jam. (Fill the canner/stockpot at least half full of enough clean, warm water so the level will be at least 1" over the top of the filled jars once they're added).
• Wash, pit and chop plums w/ skins.
• Wash and crush blackberries w/ potato masher.
• Place plums and crushed blackberries in large pot.
• Add pectin a little at a time to plums and berries, stirring constantly.
• Heat on high stirring constantly until mixture comes to a FULL boil.
• Add sugar ALL at once, stirring.
• Bring mixture back to a full hard boil, stirring constantly.
• Use potato masher to carefully further crush plums and berries in pot.
• Boil for 5 minutes.
• Skim off foam, if present.
• Place in sterilized, hot jars, leaving 1/4" headspace.
• Wipe edges of jars with clean cloth, place lids and screw on bands fingertip-tight.
• Process in a boiling water bath for ten minutes at sea level (over 1000 feet, add one minute of processing for each 1000 feet in altitude).
• Remove from water and place jars on a cloth-protected counter or cooling rack to cool undisturbed for 24 hours.
• Remove rings from sealed jars and store; put any unsealed jars in the refrigerator and use first.
