Strawberry jam
 Makes 6 -10 assorted sized jars
 Ingredients
 - 1½ kg strawberries
 - 3 tbsp lemon juice (about 1½ lemons)
 - 1½ kg preserving sugar with pectin
 - 15g butter
 
Method
 - Wash jam jars and place upside down in the oven at 100C to dry thoroughly.
 - Place a small plate in the fridge for testing the jam later.
 - Hull the strawberries and add half to a preserving pan and crush them roughly with a potato masher; add the rest of the fruit, the sugar and the lemon juice.
 - Stir all the ingredients together, well off the heat.
 - Place the pan on a low heat and stir until sugar has dissolved.
 - Add the butter.
 - Bring to a rapid, rolling boil for 4 mins.
 - When cool, spoon a little on to a chilled saucer, run a finger through the jam so that the saucer is visible.
 - If the finger line remains in the jam and the jam wrinkles it is ready. If not boil a little longer and try again.
 - Ladle into the hot jars and fill until almost full to allow for shrinkage as the jam cools. Cover the surface of each jar with a waxed disc, with the shiny side down.
 - Rinse a cellophane circle with a little water then put wetted side uppermost over the top of the jar and secure with an elastic band or a screw-top lid.
