Equipment

  • Colander
  • Large bowl
  • Preserving pan (or similar)
  • long wooden spoon
  • Potato masher (optional)
  • Digital thermometer (optional)
  • Slotted spoon
  • jam funnel
  • 8 small glass jars with lids

Ingredients

  • 2 kg crab apples halved (washed & drained, beards removed, leave stems in tact)
  • 1 unwaxed lemon sliced
  • 1.365 kg granulated sugar approx., will vary, see instructions below
  • 2.5 L water

Instructions

  • Place the halved crab apples, lemon slices and 2.5 litres of water into a preserving pan or similar.
  • Bring to the boil and then simmer for 25 – 30 mins until pulpy. Use a potato masher or side of a wooden spoon to squash the crab apples as they cook.
  • Pour the fruity liquid into a jelly bag (or see my hacks in Notes section if you don’t have one) and leave to drain over a large pan or bowl overnight. Do not, repeat not, squeeze the bag or you will have cloudy jelly.
  • The next day, measure the juice (mine yielded 1.75 L).
  • Pour juice into a preserving pan with 450 g of granulated sugar for every 575 ml of juice. The easiest way to work this out is to calculate 78% or your juice figure which will give you your sugar weight. Tip: ask Google to do the maths!
  • Place the pan over a gentle heat and stir until all the sugar has dissolved. The pan must not bubble. Drag a wooden spoon over the pan to check there are no more sugar crystals.
  • Bring the pan to a rolling boil, stirring frequently until setting point is reached, which is 105 C. My jelly reached this stage at 21 mins but this will vary so if you don’t have a digital thermometer best to check a few minutes before.
  • Remove the pan from the heat and test for set by placing a few drops of jelly on a chilled sauce and place in fridge for 30 seconds.
  • The jelly is ready if a crinkle forms when you push your finger through it. If it’s not ready, carry on boiling for a minute at a time and re-test until set is achieved.
  • Put the jelly on a low heat and remove any scum with a slotted spoon as the jelly otherwise the jelly will start to set and this process will become difficult.
  • Keep over a low heat and pots up into sterilised jars to stop the jelly setting before it reaches the jars. Small jars are best, I filled nearly 8.
  • Place lids on immediately and allow to cool.
  • Store in a cool, dark place where it will keep for 1 year. Once open store in the fridge and use within a few months.

Notes

Sterilise 8 small jars by washing in hot soapy water (or take straight from dishwasher), fill with boiling water, empty and then place in oven for 20 minutes at 140°C where you leave them until the jam is ready. Washed lids should be sterilised with boiling water and then left to drain. (If not fully dry you can pop lids in the oven along with the jars with just the fan running after the jars have had their 20 mins or heating).
To make a strainer if you don’t have a jelly bag etc, put a colander into a new pair of tights (you can sterilise in boiling water), tie the legs into a tight knot on the side and snip off the excess. You could also line a colander with clean net curtains, a tea towel or muslin.
