Why it works: Sugar and apple are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Siberian Crabs, Preserved
Ingredients
Directions
Make the syrup
Weigh the crabs and measure out the same weight in sugar.
Make a syrup by boiling the sugar with apple jelly.
Cook the crabs
Prick the crabs and add them to the boiling syrup.
Boil the crabs for a few minutes, then remove and drain them on a sieve.
Once cooled, return the crabs to the syrup and boil for a few more minutes.
Drain the crabs again as before.
Repeat this process one more time.
Finally, place the crabs in glasses or jars and pour the boiling syrup over them.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 1-octen-3-ol (mushroom, earthy).
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
- Crabs
- Form the main body of the preserve; pricking and repeated boiling let the syrup penetrate them.
- Sugar
- Sweetens the preserve and, at high concentration, helps keep it from spoiling.
- Apple jelly
- Adds pectin and fruit flavour to the syrup and helps it set and cling to the crabs.
The step that matters
Repeated boiling and draining. Each boil in concentrated sugar syrup draws water out of the crabs and replaces it with sugar. Repeating the cycle gradually builds syrup concentration throughout, which is what preserves them. Skipping or shortening cycles leaves the flesh less saturated.
Swap the apple
How well each one fits the dish's main ingredients (crab, sugar):
- Raisinfits better
- Lemonfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against crab, sugar. Candidates are from the same food group and used in at least 100 recipes.
