Why it works: Apple and brandy are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,291 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Apple Marmalade
Ingredients
Directions
Prepare the apples
Pare and core the apples, then cut them into pieces and place them in a preserving pan.
Add enough water to cover the apples and boil until they reduce to a mash.
Pass the mash through a colander.
Make the marmalade
For each pound of pulp, add 12 ounces of sugar and boil until it reaches a jelly consistency.
Test for jelly as you would for apple jelly.
Pot and seal
Once cool, transfer to pots.
Cover with paper dipped in brandy or melted mutton suet, securing with paper or bladder.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk of the pulp and the pectin that lets the mixture set.
- Sugar
- Sweetens the marmalade and helps it thicken into a jelly-like set.
- Water
- Covers the apples so they soften and break down into a mash.
The step that matters
Boiling to a jelly consistency. Apples contain pectin and acid that set the mixture, but overcooking or undercooking changes the set. Testing for a jelly stage shows when enough water has evaporated and sugar has concentrated to firm up on cooling.
Swap the apple
How well each one fits the dish's main ingredients (sugar, brandy, mutton):
- Vanillafits about as well

- Applethe original
Fit is the average pairing score against sugar, brandy, mutton. Candidates are from the same food group and used in at least 100 recipes.
