Why it works: Apple and syrup work together. They rank in the top 22% of all ingredient pairs, and cooks put them together in 742 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Apple Jelly
Ingredients
Directions
Prepare the apples
Peel and core the apples.
Place the apples in a preserving pan and add enough water to cover them.
Boil gently until the mixture reaches a marmalade consistency.
Strain the mixture through a jelly bag.
Make the jelly
Measure the same quantity of clarified syrup as the apple juice.
Boil the syrup down to caramel.
Stir in the apple juice and boil for 30 minutes.
Test the jelly by dropping a little on a plate. If it sets, it is ready.
Pot and seal
Pour the jelly into pots.
Cover the pots with brandy paper.
Tie down the pots.

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).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the pectin and acidity that help the jelly set and give it flavour.
- Clarified syrup
- Adds sweetness and body, and its sugar helps the jelly set.
The step that matters
Test the jelly for set. Jelly sets only once enough pectin and sugar are concentrated by boiling. Testing on a cold plate shows whether it will gel, so the cook avoids under-boiled, runny jelly or over-boiled, stiff jelly.
