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 ↓
Potato Yeast
Ingredients
Directions
Make the potato mixture
Grate the potatoes.
Scald the grated potatoes in boiling water.
Add sugar and coarse sea salt to the mixture.
Put the mixture in a glass or stone jar.
Ferment the yeast
Add a little yeast to make it rise.
Cork the jar well and keep it in a warm place until it ferments, about one day.
For two quarts of flour, use ½ cup of this yeast.

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: beta-damascenone (apple, rose).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch that feeds the yeast and gives the mixture body.
- Yeast
- Starts the fermentation that makes the mixture rise and become active.
- Sugar
- Gives the yeast an easily used food source to speed fermentation.
The step that matters
Keep the jar corked in a warm place until it ferments. Yeast works best in a warm environment. Too cold and fermentation stalls; sealing the jar keeps wild microbes and air out while the yeast grows.
