Why it works: Apple and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Apple Jelly
Ingredients
Directions
Prepare the juice
Filter the apple juice through felt filters if not clear.
Place the juice in a kettle and bring to a boil.
Skim off all froth.
Make the jelly
Stir in the sugar until dissolved.
Boil continuously until it jells, about 32 degrees.
Keep well skimmed during boiling.
Test for jelling by placing drops on a cold surface or checking the drop from a paddle.
When ready, fill tumblers and set aside to cool.

Shared aroma: beta-damascenone (apple, rose).
Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Apple juice
- Provides the fruit flavour and the pectin and acid that allow the jelly to set.
- Sugar
- Adds sweetness and, with the boiling, helps the jelly thicken and set firmly.
The step that matters
Boil continuously until it jells. Setting depends on reaching the right concentration of sugar and pectin, which is judged by the jelling point of about 32 degrees. Boiling too briefly leaves the jelly runny, while overboiling can make it stiff and dull. Testing drops on a cold surface helps you catch the set in time.
