Advice on jam making from The Good Housekeeping institute.

  • Always use rip but firm fruit.
  • Jam made from over-ripe fruit may not set well
  • Make sure your jars are clean, dry,warm and not cracked
  • The usual proportion is 1lb sugar to 1lb fruit.
  • Too much sugar may cause crystallisation. Too little may prevent setting.
  • There is no difference between cane and beet sugar as far as keeping quality is concerned.
  • Jam made with low-acid fruits such as strawberries or cherries may need extra acid to ensure satisfactory setting.
  • Refer to a good recipe book.
  • When making marmalade, make sure that the peel is really soft before adding the sugar.
  • Warming the sugar before adding to fruit shortens coking time and improves set and colour.
  • All the sugar must be dissolved before the am is brought to the boil. Then boil rapidly until seting point is reached.
  • A knob of butter added when the sugar is dissolved helps to recude any whitish scum which may occur.
  • To test jam for setting, try a little on a cold plate.
  • The surface should crinkle when pushed by a fingertip. To prevent fruit such as strawberries rising to the top of the jars, let the jam cool slightly and stir it, before filling jars.
  • Fill warmed jars to the brim with hot jam.Immediately insert waxed circles with the waxed surface in close contact with the jam while it is still hot.
  • Covers should be put on when jam is either hotor cold, but never when it is tepid as this can cause mould growth.
  • Wipe rim. Moisten one side of transparent cover. Place in position, damp side up. Secure with rubber band.
  • As the cover dries, it will contract to give a tight seal.
  • Make sure your jars are clean and dry before affixing labels.
  • Store your jam in a cool, dry, dark, well-ventilated place.
