Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Raspberry or Blackberry Vinegar
Ingredients
Directions
Steep the berries
Crush the berries well in a large crock using a wooden mallet.
Cover the crushed berries with cider vinegar, 1 inch deep.
Place the crock in the hot sunshine for a day.
Leave it in the cellar overnight.
Stir the mixture six times during the day.
Strain and squeeze the berries to extract the liquid, then discard the solids.
Repeat crushing and steeping with another gallon of mashed berries.
Leave it in the sun and cellar as before.
Make the syrup
Measure the liquid obtained and add 1 pint of water for each quart of liquid.
For every pint of water added, mix in 5 pounds of sugar.
Pour the mixture into a porcelain-lined or agate-iron kettle.
Heat over the fire, stirring until the sugar dissolves.
Bring the mixture to a boil.
Boil hard for 1 minute to remove scum.
Skim the mixture.
Remove from heat.
Strain the mixture.
Bottle
Bottle while still warm.
Seal the bottles with a mixture of beeswax and rosin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Berries
- Provide the flavour and colour that the vinegar draws out during steeping.
- Cider vinegar
- Acts as the solvent that extracts juice and flavour from the crushed berries.
- Sugar
- Sweetens the finished vinegar and balances its acidity.
The step that matters
Boil hard for 1 minute to remove scum. Boiling the sweetened liquid brings scum and impurities to the surface, which must be skimmed off so the finished vinegar stays clear and keeps well.
