Why it works: Raisin and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 12,481 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raisins
- Add fruity sweetness and body to the infusion as they break down during steeping.
- Lemons
- Supply acidity and aroma from the juice and peel oils.
- Loaf sugar
- Adds sweetness and helps preserve the liquid during the standing period.
The step that matters
Let it stand for 4 to 5 days, stirring daily. Steeping is what draws flavour from the lemon peel and raisins into the water. Stirring daily keeps the solids evenly distributed so the infusion extracts uniformly rather than unevenly at the bottom.
Swap the lemon
How well each one fits the dish's main ingredients (raisin, sugar):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Lemonthe original
Fit is the average pairing score against raisin, sugar. Candidates are from the same food group and used in at least 100 recipes.
