Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

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: 2-nonenal (fatty, green).
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
- Pippins or bell-flowers
- Apples that supply the fruit itself, which softens and turns clear as it cooks in the syrup.
- Sugar
- Provides sweetness and, as the syrup boils down, thickens it and helps preserve the fruit.
The step that matters
Remove the fruit before boiling the syrup until thick. Boiling the syrup down concentrates the sugar as water evaporates. If the fruit stays in during this longer boil, it keeps cooking, breaks down and becomes mushy.
