PREPARING JARS FOR POTTING UP JAM OR MARMALADE
Into well washed jars pour about 1 cm (half an inch) of boiling water, place in microwave on full power for 3 – 4 mins until the water boils in the jars.
Take care and tip them out well and stand to evaporate the last bit of water while you re-heat the jam mix
