Why it works: Apple and bread are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 1,790 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Ohst Essig — Fruit Vinegar
Ingredients
Directions
Prepare the juice
Crush the fruit well with a stamper or cider-press.
Pour 4 gallons of boiling water over the crushed fruit in a suitable tub.
Stir well and let it stand in a warm place for a week, skimming off impurities as fermentation rises.
Strain the mixture through fine linen, pressing the pulp to extract juice.
Ferment and bottle
Put the juice in a barrel, stir in 1 pint of yeast, and add a piece of bread.
Ensure the barrel is full, loosely put in the bung, and cover with a piece of flannel.
Let it stand in a warm place for 1 to 6 weeks until the vinegar is ready to bottle.

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.

What each ingredient does
- Fruit
- Provides the sugars and juice that ferment into vinegar.
- Yeast
- Starts the fermentation that converts the fruit sugars into alcohol.
- Bread
- Adds nutrients and a starter that helps the fermentation along.
The step that matters
Keep the barrel full and loosely bunged. A full barrel limits contact with air that could spoil the liquid, while a loose bung lets gas escape without letting in too much contamination. Vinegar bacteria need air to convert alcohol into acetic acid, so the cover must still allow airflow.
