Our local fruit farm is certainly getting lots of business from us this year. We had another trip at the weekend to collect raspberries for my little ones favourite jam.
While your jars are sterilising in the oven pop the sugar in a glass bowl in too so it can warm up.
Put the raspberries into a large pan and simmer for 5 - 10mins until the fruit is has reduced down to juice and pulp. Add the warmed sugar and stir to dissolve.
Increase the heat and bring to a rolling boil. Boil for 5 -10mins until it has reached 104 degrees C (or do the plate test).
Pot the jam into the sterilised jars, seal and label.
