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 apples
Cut the sour apples into pieces without peeling them.
Place the apples in a jar and cover them with water.
Cook the jar in the oven or on the range until the apples are soft.
Squeeze the water from the apples.
Make the jelly
For every 9 pints of liquid, add 4 pounds of brown sugar.
Boil gently until the mixture jellies.
Pour the jelly into molds or pots for storage.

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
- Sour apples
- Provide pectin and acidity that help the mixture set into a jelly.
- Brown sugar
- Adds sweetness and bulk, and helps the jelly thicken and set as it boils.
The step that matters
Boil gently until the mixture jellies. Sugar and pectin only set when the liquid reaches the right concentration. Boiling too briefly leaves it runny, while boiling too hard can scorch the sugar and darken the flavor.
