Why it works: Rose and geranium work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 64 recipes. Both carry cis-rose oxide, which smells green, flower. The science ↓
Apple Jelly
Ingredients
Directions
Prepare the apples
Cut the apples into quarters after peeling and coring them.
Place the apples in a pot with enough water to prevent burning, about 1 quart.
Make the jelly
Cook the apples thoroughly, then strain the mixture through a flannel bag without squeezing.
For each pint of juice, add ¾ pound of sugar.
Boil the juice for 10 minutes, then add the sugar and boil for an additional 20 minutes.
If desired, add the juice and peel of 2 fresh lemons.
Optionally, add a few rose geranium leaves and boil for 2-3 minutes before finishing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pippin apples
- Provide natural pectin and tartness that help the juice set into a jelly.
- Sugar
- Sweetens the jelly and, with boiling, helps it thicken and set.
- Lemons
- Add acidity that supports pectin setting and brightens the flavour.
The step that matters
Boil the juice with the sugar. Sugar and acid must be boiled to the right concentration for pectin to gel. Boiling too briefly leaves the jelly runny, while overcooking can make it stiff and dull in flavour.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (apple, sugar, rose, geranium):
- Vanillafits better
- Strawberryfits better
- Orangefits better
- Lemonthe original
Fit is the average pairing score against apple, sugar, rose, geranium. Candidates are from the same food group and used in at least 100 recipes.
