Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Syrup of Lemon
Ingredients
Directions
Make the syrup
Combine the lemon juice and capillaire in a pot.
Bring to a boil and simmer for 1 hour, skimming off any scum that rises.
Bottle and store
Once finished, pour the syrup into small bottles and cork them tightly.
Store in a cool, dark place; it will keep for years.

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: ethanol (alcoholic, ethereal).
Lemon and sugar 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
- Lemon juice
- Provides the sharp acidity and bright flavour that defines the syrup.
- Capillaire (sugar syrup)
- Provides sweetness and body, balancing the acidity of the lemon juice.
The step that matters
Simmering for 1 hour and skimming. Simmering concentrates the flavour and thickens the syrup slightly, while skimming removes impurities that rise to the surface and could spoil the syrup during storage.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, syrup):
- Vanillafits better
- Raisinfits better
- Pearfits about as well
- Lemonthe original
Fit is the average pairing score against sugar, syrup. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
