PRESERVING
1. DO NOT use a pan that overlaps the perimeter of
the hob trim.
To allow for a full rolling boil, the pan should be
no more than one third full when all the
ingredients have been added. It is better to use
two pans rather than overfill one, or use half
quantities.
Use firm fruit or vegetables and wash well before
using.
Preserving sugar gives clear jam, however
granulated sugar is cheaper and gives equally
good flavour.
Crystallization may be caused if sugar is not
completely dissolved before bringing jam to the
boil. Over boiling will affect the flavour, setting
properties and colour of the jam.
To test jam for setting:
If a jam thermometer is available, boil jam to
104°C. Marmalade should be boiled to 106°C.
If a jam thermometer is not available, remove
pan from heat, place sample of jam on a cold
dish and cool quickly (i.e. in a freezer or frozen
food storage compartment of a refrigerator).
When cold, it will crinkle and hold the mark of a
finger run through it, if it is ready.
The scum should be removed as soon as
possible after setting, but marmalade should be
allowed to cool before potting to prevent the peel
rising.
