Why it works: Rye and sugar work together. They rank in the top 25% of all ingredient pairs, and cooks put them together in 535 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Cider Vinegar
Ingredients
Directions
Start the vinegar
Mix 6 quarts of rye meal into a barrel of strong hard cider.
Add 1 gallon of whiskey and cover the cask loosely.
Place the cask in a sunny, airy spot for 4 weeks.
Draw off and replenish
When drawing off vinegar, replenish with the same amount of cider and add 1 pint of whiskey.
Variations
For a stronger vinegar, mix cider with 1 pound of strained honey per gallon and let it stand for 5-6 months.
For white vinegar, mix 5 gallons of water, 2 gallons of whiskey, and 1 quart of strong yeast, stirring in 2 pounds of powdered charcoal.
Leave the bung loose during fermentation for 4 months, then draw off the vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider
- Supplies the sugars and alcohol that acetic acid bacteria convert into vinegar.
- Whiskey
- Adds alcohol that feeds the fermentation into acetic acid.
- Rye meal
- Provides starches and nutrients that support the fermentation.
- Strong yeast
- Starts alcoholic fermentation in the white vinegar mixture.
The step that matters
Leave the cask loosely covered in a sunny, airy spot. Vinegar forms through acetic acid bacteria, which need oxygen to turn alcohol into acetic acid. A tightly sealed cask blocks air and stalls the process, while a loose cover lets air in.
