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 ↓
Elderberry Preserve
Ingredients
Directions
Make the syrup
Make a syrup by combining the lemon juice, grated rind, and as little water as possible.
Skim the syrup if necessary.
Cook and fill the jars
Add the elderberries and cook for 20 minutes.
Strain the berries into jars or glasses.
Boil the syrup until it reaches a jelly consistency and pour it over the fruit until the jar is full.
Cover the jars
Cover the jars after 24 hours. If using an open-mouthed jar, place a piece of thin paper over it and tie a cloth or thick paper cover.

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.

What each ingredient does
- Elderberries
- Provide the main fruit flavour and the body of the preserve.
- Sugar
- Adds sweetness and, once concentrated, helps the preserve set and keep.
- Lemon
- Adds acidity that brightens the flavour and supports setting.
The step that matters
Boil the syrup to a jelly consistency. Sugar and fruit set only when the syrup reaches roughly the concentration needed for gelling. Stopping early leaves the preserve runny, while boiling too long makes it stiff and can cause sugar to crystallise.
