Equipment

  • 1 slow cooker - I used a 4 to 6 person (4.7 litre) CrockPot.
  • 2 couple of tea plates or saucers placed in the fridge before you start making the jam.
  • 1 Ladle
  • 1 jam funnel – definitely something I wouldn’t be without as it saves a lot of mess and waste.
  • 4 sterilised jam jars and lids.
  • 1 immersion blender - I used my Bamix. Alternatively, you could use a potato masher which won't give such a smooth jam or you can omit this step if you prefer.

Ingredients

  • 1.2 kg peaches skinned and chopped
  • 2 tablespoons lemon juice
  • 1 kg jam sugar

Instructions

  • Place a couple of saucers or plates in the fridge ready to test your jam later.
  • Add chopped peaches and lemon juice to the slow cooker pot and stir.
  • Add jam sugar and stir. Pop on the lid and cook on low for one hour.
  • Remove lid and stir. (Don’t worry, the sugar is unlikely to have fully dissolved yet)
  • Scrape down any sugar and replace the lid and cook on low for another hour. Stir your jam mixture and turn up your slow cooker to high – the sugar will have fully dissolved by now.
  • Replace the slow cooker lid but this time prop it open a little with a wooden spoon to allow the steam to escape.
  • Cook on high for 2 to 3 hours until set.
  • Check after 2 hours: drop a small amount of jam on to your chilled saucer. Allow to cool for a couple of minutes and then push gently with your finger tip. If the jam crinkles, setting point has been reached.
  • Mine did need the 3 hours but it very much depends on your slow cooker.
  • Transfer to sterilised jars and screw on lids.
  • Leave to cool.
  • Store in a cool dry place away from direct sunlight and once opened store in the fridge.

Notes

  • The recipe works well with nectarines too.
  • Makes about 4 x 226g / 8 oz jars.
  • Slow Cooker Peach Jam will keep for up to a year in a cool, dry place away from direct sunlight. Once opened, refrigerate and use within 4 weeks.
