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 ↓

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
- White currants
- Provide the fruit flavour and pectin that give the jam its body as it sets.
- White sugar
- Sweetens the jam and helps preserve it and thicken it as it cooks.
- Lemon juice
- Adds acidity that brightens the flavour and helps the pectin set.
The step that matters
Boiling the currants and sugar together. Boiling must be steady enough to reach the setting point, since too little cooking leaves the jam runny, while stirring gently prevents the sugar from scorching on the bottom of the pan.
Swap the white currant
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better

- White 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.
