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 ↓
Fruit Jelly
Ingredients
Directions
Make the jelly
Break up the isinglass and boil it in 1 pint of water until dissolved.
Add 1 quart of boiling water and sweeten with white sugar to taste.
Strain one-third of the mixture into a deep bowl and refrigerate to harden.
Layer and set
Once firm, sprinkle a layer of sweetened berries or fruit.
Add half of the remaining jelly, then another layer of fruit, and top with the rest of the jelly.
When cold, turn out onto a dish to serve.

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
- Russian gum isinglass
- Sets the liquid into a firm, wobbly gel when cooled.
- Berries or fruit
- Adds flavour and colour, and forms distinct layers within the jelly.
The step that matters
Strain one-third of the mixture and let it harden fully before adding fruit. Isinglass sets only as the liquid cools, so the base layer must be firm before fruit is added. If the jelly is still liquid, the fruit sinks and the layers blur together.
