PRESERVE PLUMS RECIPES

Steps:

• Put the plums, lemon juice and 150ml/5fl oz water in a heavy-based saucepan or preserving pan. Bring to a simmer and cook gently for about 5 minutes until the plums are beginning to soften a little. Add the sugar, a third at a time, stirring until dissolved, then remove the pan from the heat. Cover the pan and leave for a couple of hours or overnight so the mixture can cool – the plums will sink from the surface as they become heavier.
• Return the pan to the heat, stirring to remove any sugar clumps on the base of the pan, and carefully bring the mixture to the boil. Increase the heat and bring to a rapid boil for approximately 10 minutes until the setting point is reached (see tips). Remove from the heat and leave to rest for 5 minutes to allow the fruit to settle.
• Tip the jam into a wide-necked jug with a good pouring lip, then fill four sterilised jars to the brim. Seal immediately with the lids and store in a cool, dark place. The jam is best eaten within 1 year.

Steps:

• Sterilise the jars and any other equipment before you start (see tip). Put a couple of saucers in the freezer, as you’ll need these for testing whether the jam is ready later (or use a sugar thermometer). Put the plums in a preserving pan and add 200ml water. Bring to a simmer, and cook for about 10 mins until the plums are tender but not falling apart. Add the sugar, ground cinnamon and lemon juice, then let the sugar dissolve slowly, without boiling. This will take about 10 mins.
• Increase the heat and bring the jam to a full rolling boil. After about 5 mins, spoon a little jam onto a cold saucer. Wait a few seconds, then push the jam with your fingertip. If it wrinkles, the jam is ready. If not, cook for a few mins more and test again, with another cold saucer. If you have a sugar thermometer, it will read 105C when ready.
• Take the jam off the heat and add the cinnamon sticks (if using) and the knob of butter. The cinnamon will look pretty in the jars and the butter will disperse any scum. Let the jam cool for 15 mins, which will prevent the lumps of fruit sinking to the bottom of the jars. Ladle into hot jars, seal and leave to cool. Will keep for 1 year in a cool, dark place. Chill once opened.
