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 ↓

Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and cook the apples
Dip each apple quarter into clear water.
Place the quarters in a jar and cook in the oven at 300°F (150°C) until tender.
Make the jelly
Strain the juice from the cooked apples.
Boil the strained juice with 1 pound of sugar until it reaches a jelly consistency.

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
- Apples
- Provide pectin and natural juice that sets into a jelly when cooked and strained.
- Sugar
- Sweetens the jelly and helps it set to a firm, spreadable consistency when boiled.
The step that matters
Boiling the juice to jelly consistency. Sugar and pectin only gel when the mixture reaches the right concentration. Too little boiling leaves a runny jelly, while overcooking can make it stiff or cloudy. Testing for a gel point, such as a wrinkle on a cold plate, helps the cook stop at the right moment.
