While you are making the marmalade,
place three small saucers into the freezer. When ready to test for gel stage, remove
one saucer and place a spoonful of marmalade onto the cold surface. Within 30
seconds marmalade will thicken and develop a skin (and when pushed through the
marmalade, it will be thick and not runny). If still loose, continue boiling
marmalade for around 5 minutes or until ready to test with the second saucer.
TIP: Forgotten to put the plates into
the freezer? Use a glass filled with iced water to chill several teaspoons to
check the consistency instead.
NOTES: There are several other methods for testing the gel stage of jams, jellies and marmalades - however if you are reducing the sugar content of your preserves, the gel stage may not occur at the same temperature (i.e. will need longer boiling period). Another method is called "sheeting" where the marmalade collects on an angled spoon and drips thickly.
