Watermelon Jelly
Practical Action
placed in water to cool down the jelly so that it does not keep cooking in the jar. The water
should not be too cold or the glass may crack. Also, the water level must be kept below the
lid of the jar. The gel starts to form as the temperature of the jelly reduces (about 55°C) and
continues until it is cold. The jars should not be moved or shaken while they are cooling or
the gel will not form and the jelly will not set.
Storage
Jam and jelly that is hygienically prepared, boiled until it reaches the correct final total
soluble solids (68%) and which is packaged in sterilised glass jars can be stored for up to a
year so long as it is kept in a cool place away from direct sunlight. Jam or jelly that is
packaged in plastic containers has a shorter shelf life – up to 4 months.

Weighing machines
It is important to have accurate weighing machines. Quite often more than one machine is
required - -a large one to weigh the fruit and a small one for weighing out the dry ingredients
such as pectin and spices.
