Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Apple Jelly
Ingredients
Directions
Prepare the juice
Core and cut the apples into quarters.
Boil the apples with the lemon rind until tender.
Drain off the juice and strain it through a jelly bag.
Make and set the jelly
To each pint of juice, add 2 pints of sugar and 5 ounces of soaked gelatine simmered in 5 pints of water.
Boil the mixture slowly for 15 minutes and strain into molds.
Once cold, turn out the jelly and serve with whipped cream or custard.
Clarify if needed
If the jelly is not clear, beat an egg white, add it, bring to a boil, skim, and strain again.

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 natural pectin and the fruit flavour that forms the jelly's body.
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Sugar
- Adds sweetness and helps give the jelly a smooth, set texture.
- Lemon rind
- Adds aromatic oils and a bright note that lifts the apple flavour.
- Egg white (in the method)
- Binds fine particles so they can be skimmed off, clearing the jelly.
The step that matters
Boil the mixture slowly for 15 minutes. Gently simmering keeps the jelly clear, while vigorous boiling can cloud it and weaken the gelatine's setting power, so the jelly may not firm properly.
