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
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Prepare jars and lids for canning.
Make the jelly
In a large pot, combine apple juice and fruit pectin, and stir well.
Bring the mixture to a boil over medium heat, stirring constantly.
Add granulated sugar and coarse sea salt, and stir until dissolved.
Bring to a rolling boil and cook for 1 minute.
Remove from heat and skim off any foam.
Jar and process
Pour into prepared jars, leaving ¼ inch headspace.
Seal jars and process in a boiling water bath for 5 minutes.

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: 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.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fruit pectin
- Sets the juice into a gel as it cooks with sugar and acid.
- Granulated sugar
- Provides sweetness and helps the jelly set and keep its texture.
- Apple juice
- Supplies the liquid and flavor base that the jelly is built on.
The step that matters
Bring to a full rolling boil and cook for 1 minute. Pectin needs sugar and a hard boil to set properly. Boiling only gently or for less time can leave the jelly runny, while the set depends on reaching a true rolling boil.
