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 ↓

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
- Ground cherries
- Provide the main fruit flavor and pectin-containing body for the jam.
- Sugar
- Sweetens the jam and helps it thicken and keep as it cooks down.
- Lemons
- Add acidity that brightens flavor and helps the jam set.
The step that matters
Cook over low heat until thick. Low heat cooks the jam down gradually, reducing the water and concentrating sugar and fruit without scorching. Cooking time is long, so the jam must be checked for thickness before sealing.
