Why it works: Rhubarb and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 1,852 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

Ingredients
Directions
Prepare the infusion
Bruise the rhubarb stalks and pour them into 5 gallons of water.
Let the mixture stand for 24 hours, then strain it.
Ferment
Add 9 pounds of brown sugar and 1 small cup of yeast to the strained liquid.
Keep the mixture warm for one month.
After a month, strain it again and store in a cask until it is sour enough to use.

What each ingredient does
- Rhubarb
- Supplies the tart flavor and acidity that give the vinegar its character.
- Brown sugar
- Provides the sugar that yeast ferments into alcohol, which then turns sour.
- Yeast
- Starts the fermentation that converts sugar into alcohol for the vinegar to develop from.
The step that matters
Keeping the mixture warm for a month. Fermentation proceeds slowly and depends on steady warmth; if the mixture gets too cold, the yeast works poorly and the sugar may not fully convert. Store the cask until the vinegar is sour enough to use.
