Why it works: Rhubarb and lemon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 546 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Rhubarb Wine
Ingredients
Directions
Prepare the rhubarb
Wipe the rhubarb with a damp cloth and cut it into short lengths, leaving the peel on.
Crush the rhubarb thoroughly with a wooden mallet or potato masher in an earthenware or wooden vessel.
Pour the cold water over the crushed rhubarb and cover it.
Let it sit for 10 days, stirring daily.
Make and age the wine
Strain the liquid into another vessel, then add the sugar, lemon juice, and rind.
Stir until the sugar dissolves.
Transfer the mixture into a cask and add the isinglass dissolved in a little warm water.
Cover the bunghole with a folded cloth for 10 days.
Securely bung the cask and let it sit undisturbed for 12 months.
After 12 months, rack off the wine into bottles and use.

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: 1-penten-3-one (fish, pungent).
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
- Rhubarb
- Provides the tart flavour and the fruit base that the wine is made from.
- Sugar
- Supplies sweetness and the sugar that yeast ferments into alcohol.
- Isinglass
- Fining agent that helps clear the wine by settling suspended particles.
The step that matters
Securely bung the cask and leave it undisturbed for 12 months. Fermentation gives off carbon dioxide, and the wine must stay sealed and still so it can clear and mature. Disturbing it early can stir up sediment and cloud the wine.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, lemon):
- Cinnamonfits better
- Gingerfits better
- Marjoramfits better
- Rhubarbthe original
Fit is the average pairing score against sugar, lemon. 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.
