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 syrup and fruit
Boil the sugar in water for 20 minutes.
Pour the boiling syrup over the strawberries and let them sit overnight.
Soak the isinglass in water to clarify it.
Drain the syrup from the strawberries and mix in the red-currant juice and lemon juice.
Set the jelly
When the isinglass is nearly cold, combine it with the fruit mixture and add more sugar if desired.
Pour the mixture into molds and cover with crushed ice.

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.

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
- Isinglass
- Gelatin-like protein that sets the liquid into a firm jelly when chilled.
- Loaf sugar
- Adds sweetness and body to the syrup, and helps the jelly hold its shape.
- Scarlet strawberries
- Provide the main fruit flavour, colour and aroma of the jelly.
- Red-currant juice
- Adds tart acidity and a deeper colour to balance the sweet strawberry flavour.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the sweetness.
The step that matters
Combine the isinglass when it is nearly cold. If the isinglass is too hot it can weaken its setting power, and if it is too cold it may begin to gel before it is evenly mixed, leaving lumps or an uneven set.
Swap the currant
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better
- Vanillafits better
- Currantthe original
Fit is the average pairing score against sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
