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 ↓
Cowslip Wine, Superior
Ingredients
Directions
Prepare the liquor
Boil sugar, lemon juice, water, and egg whites for 30 minutes, skimming frequently.
Place cowslips in a clean, dry tub.
Pour the boiling mixture over the cowslips.
Optionally, add thin rinds of lemons, avoiding any white pith.
Stir with a wooden stick for a few minutes.
Let the mixture cool to lukewarm.
Ferment
Add a thin slice of dry toasted bread spread with fresh yeast.
Let the mixture stand in a cool place for 3-4 days.
Strain the liquor.
Squeeze the flowers to extract all goodness.
Cask and bottle
Transfer the wine to a cask rinsed with pale brandy.
Bung loosely until fermentation stops.
Bung securely.
Bottle the wine after 3 months.

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
- Sugar
- Provides the sweetness and the food for yeast to turn into alcohol.
- Cowslips
- Supply the flower flavour and aroma that define the wine.
- Lemon juice
- Adds acidity that brightens the flavour and supports a clean fermentation.
- Egg whites
- Bind impurities during boiling so they rise and can be skimmed off, clarifying the liquor.
- Yeast
- Converts the sugar into alcohol and carbon dioxide during fermentation.
The step that matters
Bung loosely until fermentation stops. While fermentation is active it releases carbon dioxide, which can build pressure and break a tightly sealed vessel. Sealing too early can burst the cask, while sealing only after activity ends keeps the wine stable.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
