Sugar Vinegar
Ingredients
Directions
Prepare
Boil the spring water with coarse sugar and skim off any scum.
Let the mixture cool, then add the yeast toast.
Ferment
Allow it to ferment for 1-2 days.
Transfer to a bag or barrel, covering the bung-hole with a piece of tile or slate.
Age and bottle
Place it in a sunny spot and let it sit until July or August.
If not sour enough, let it sit for an additional month before bottling.

The flavor team
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.

Shared aroma: ethanol (alcoholic, ethereal).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coarse sugar
- Provides the sugar that the yeast converts during fermentation, producing the sour acids of the vinegar.
- Yeast toast
- Supplies the yeast and microbes that start the fermentation of the sweet liquid.
The step that matters
Let the mixture cool before adding the yeast toast. Yeast cells are killed or weakened by heat, so adding the yeast to hot liquid can stop fermentation before it starts. Cooling first keeps the culture alive to begin converting the sugar.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
