Why it works: Lemon and apple are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Crab Apple Jelly
Ingredients
Directions
Prepare the fruit
Wash and quarter large Siberian crabs, but do not core.
Cover to the depth of an inch or two with cold water, and cook to a mush.
Extract the juice
Pour into a coarse cotton bag or strainer, and when cool enough, press or squeeze hard to extract all the juice.
Take a piece of fine Swiss muslin or crinoline, wring out of water, spread over a colander placed over a crock.
With a cup, clip the juice slowly in, allowing plenty of time to run through.
Repeat this process twice, rinsing out the muslin frequently.
Cook the jelly
Add the strained juice of four lemons to a peck of apples, and add three-quarters of a pound of sugar to each pint of juice.
Boil the juice for ten to twenty minutes.
While boiling, sift in the sugar slowly, stirring constantly, and boil five minutes longer.
This is generally sufficient, but it is always safer to "try it," and ascertain whether it will "jelly."
This makes a very clear, sparkling jelly.

Sugar and apple 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
- Siberian crabs
- Supply natural pectin and acid that help the juice set into a jelly.
- Lemons
- Add acidity that supports setting and brightens the flavour.
- Sugar
- Sweetens the jelly and helps it set into a firm gel.
The step that matters
Testing for set. Sugar must be added slowly while stirring, and the juice boiled long enough, so it dissolves and reaches the concentration needed to gel. Testing a spoonful shows whether it will set before it is poured into jars.
Swap the apple
How well each one fits the dish's main ingredients (sugar, crab, lemon):
- Limefits better
- Orangefits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against sugar, crab, lemon. Candidates are from the same food group and used in at least 100 recipes.
