What each ingredient does
- Apples
- Provide natural pectin and acid, which help the juice set into a jelly.
- Sugar
- Adds sweetness and helps the pectin form a firm gel while preserving the jelly.
The step that matters
Boil quickly after adding the sugar. Pectin needs sugar and a rapid, hard boil to set. If the mixture boils gently or too briefly, the jelly may stay runny.
