Equipment

  • 2 Saucers
  • 1 Digital scale
  • 1 potato masher
  • 1 Wooden spoon
  • 1 Large saucepan
  • 1 teaspoon
  • 1 Large metal spoon
  • 1 small ladle or jam funnel
  • 1 Table knife
  • 1 Paring knife
  • 1 240 ml glass jar and lid

Ingredients

  • 230 g Hulled strawberries washed & dryed (1 punnet)
  • 230 g Granulated sugar equal to prepared strawberry weight
  • 1 tsp Lemon juice freshly squeezed
  • A knob of unsalted butter optional

Instructions

  • Put the strawberries in a large saucepan and crush with a potato masher (leave some texture).
  • Add the sugar and lemon juice.
  • Heat gently, stirring with a wooden spoon until all the sugar has dissolved.
  • Increase heat to bring to a rolling boil and then time for 5 minutes whilst stirring with a wooden spoon (to stop jam from sticking to pan)..
  • Remove pan from heat.
  • Next, test for set by placing a few drops of jam on a chilled saucer and place in fridge for 30 seconds.
  • Then run your finger through the jam on the saucer and if it forms a crinkle and is tacky it’s ready.
  • If not boil for another minute and retest until ready.
  • Skim any scum from the surface with a metal spoon and add a small knob of butter to disperse any remaining scum if you wish.
  • Ladle into a 240 ml sterilised jar and seal with lid immediately.
  • Once cool, store in a cool, dry, dark place.

Notes

Before you start: 
Put 2 saucers in the freezer.
Sterilise jar 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 until the jam is ready. Washed lid should be sterilised with boiling water and then left to drain.
