Why it works: Peach and lemon work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 947 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Peach Maemalade
Ingredients
Directions
Prepare the fruit
Peel, pit, and weigh the peaches.
Heat the peaches slowly to extract the juice, stirring often with a wooden spoon.
Once hot, boil quickly for 45 minutes, stirring continuously.
Make the marmalade
Add ¾ pound of sugar for each pound of fruit and boil for an additional 5 minutes, skimming off any foam.
Add the lemon juice and the water from the boiled peach kernels.
Stew everything together for 10 more minutes, stirring until smooth.
Jar and seal
Pour the hot marmalade into airtight cans or glass jars, sealing them when nearly cool.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Peaches
- Provide the fruit, pectin and flavor that form the marmalade's body.
- Sugar
- Sweetens the marmalade and helps it thicken and keep as a preserve.
- Lemon juice
- Adds acidity that brightens the flavor and supports gel setting.
The step that matters
Skimming foam after adding sugar. Foam forms as the sugar boils into the fruit and can cloud the marmalade and spoil its texture. Removing it keeps the preserve clear and smooth.
Swap the lemon

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