Ingredients
Directions
Make the mixture
Pour boiling water over brown sugar and stir until it cools to the warmth of new milk.
Transfer the mixture to a large pickle jar.
Place the vinegar plant in the jar.

Allow the vinegar to ferment for 6 weeks to 3 months.
Store the jar in a warm place.

What each ingredient does
- Brown sugar
- Supplies the sugar that the culture ferments into acetic acid, which gives vinegar its sourness.
- Vinegar plant
- Is the living culture of acetic acid bacteria that converts the sweet liquid into vinegar.
The step that matters
Cool the sugar water to the warmth of new milk before adding the plant. Boiling-hot liquid can kill the bacteria in the vinegar plant. Cooling it to warm lets the culture survive and start fermenting the sugar into acetic acid.
