Why it works: Potato and sugar are a kitchen classic. They rank in the top 30% of all ingredient pairs, and cooks put them together in 3,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Dr. Hunter's Instructions for Making Potato Yeast
Ingredients
Directions
Prepare the potatoes
Boil the potatoes until thoroughly done.
Skin and mash the potatoes until smooth.
Add enough hot water to achieve the consistency of common yeast.
Run the mixture through a colander.
Ferment
When just warm, stir in the brown sugar and common yeast.
Keep the mixture warm until it has finished fermenting, about 24 hours.

What each ingredient does
- Mealy potatoes
- Provide starch and body, forming the base that the yeast feeds on.
- Brown sugar
- Feeds the yeast, giving it fuel to produce gas and drive fermentation.
- Common yeast
- Starts the fermentation that makes the mixture rise and turn active.
The step that matters
Stir in the yeast only when the mixture is just warm. Yeast is killed by high heat, so adding it to a mixture that is too hot can stop fermentation, while a mixture that is too cool slows it down. Warm, not hot, keeps the culture alive and active.
