What each ingredient does
- Primroses
- Contribute the flowers' delicate floral aroma and flavour to the finished vinegar.
- Brown sugar
- Supplies the sugar that the yeast ferments into alcohol, the first step toward vinegar.
- Fresh yeast
- Starts fermentation by converting the sugars into alcohol.
The step that matters
Add the yeast before the mixture cools completely. Yeast is killed by very high heat, so the liquid must be cool enough to be safe for it, yet still warm enough for the yeast to become active and start fermenting well.
