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
Make the potato base
Boil the potatoes until thoroughly cooked, then skin and mash them until smooth.
Add enough hot water to achieve the consistency of common yeast.
Run the mixture through a colander.
Ferment
Stir in the brown sugar.
When the mixture is just warm, add the common yeast.
Keep the mixture warm until fermentation is complete.
In 24 hours, the yeast will be ready for use.

What each ingredient does
- Mealy potatoes
- Provide starch and body, and the food the yeast ferments into a thick, active starter.
- Brown sugar
- Feeds the yeast, giving it the sugar it needs to ferment and produce gas.
- Common yeast
- Starts the fermentation that makes the mixture rise and turn active.
The step that matters
Keep the mixture warm until fermentation is complete. Yeast works fastest within a warm range; if the mixture cools, fermentation slows and the starter may not become active in time.
