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 ↓
Strawberry Jelly
Ingredients
Directions
Prepare the juice
Place strawberries in an earthen pan and mash them with a wooden spoon.
Mix in the pounded sugar and let it infuse for 1 hour to draw out the juice.
Add water and lemon juice if needed to balance sweetness.
Strain the mixture through a clean bag to obtain clear juice.
Set the jelly
Mix the melted isinglass with the cold juice.
Test the thickness by placing a small amount in a mould over ice.
If thick enough, pour the mixture into a large mould, cover with ice, and chill.

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
- Strawberries
- Provide the main flavour, colour and fruit pulp for the jelly.
- Pounded sugar
- Adds sweetness and helps draw out juice from the mashed strawberries.
- Isinglass
- Gelatine-like setting agent that firms the cold juice into a jelly.
- Lemon juice
- Adds acidity to balance the sweetness of very ripe strawberries.
The step that matters
Testing the thickness over ice. Isinglass sets only as the liquid cools, so a test on ice shows whether the mixture will firm. Pouring before it is ready risks a runny jelly, while waiting too long can make it hard to pour evenly.
