Ingredients
Directions
Prepare the apple juice
Peel and core the apples.

Boil gently until they reach a marmalade consistency.
Strain the mixture through a jelly bag.
Make the jelly

Boil the syrup down to a caramel consistency.
Stir in the apple juice and boil for 30 minutes.
Test the jelly by dropping a little on a plate.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: ethanol (alcoholic, ethereal).

What each ingredient does
- Juicy sharp apples
- Natural pectin and acid help the juice set into a firm, bright jelly.
- Clarified syrup
- Sugar adds sweetness and, when concentrated, helps the jelly set.
The step that matters
Test the jelly by dropping a little on a plate.. Pectin and sugar must reach the right concentration to gel. Undercooked jelly stays runny, while overcooked jelly becomes stiff and can taste caramelised, so testing shows when it is ready.
