What each ingredient does
- Loaf sugar
- Sugar helps the juice set into a firm gel and adds sweetness.
- Fruit juice
- Provides the liquid, plus natural pectin and acid that help the jelly set.
The step that matters
Boil quickly until it jellies. Sugar and pectin set into a gel only at the right concentration and temperature. Boiling too briefly leaves the jelly runny, while boiling too long can overconcentrate it, making it stiff and dull in colour and flavour.
