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 ↓
Starter Yeast
Ingredients
Directions
Prepare the starter
In the evening, boil enough potatoes to make 1 pint when mashed very fine.
Save the potato water and add enough more water to make 3 pints.
Add salt, sugar, and yeast to the potatoes and stir well.
Rise and keep
Cover and let rise overnight.
In the morning, save 1 pint for the next baking.

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.

What each ingredient does
- Yeast
- Ferments the sugars and produces gas that makes the starter rise and become bubbly.
- Mashed potatoes
- Provide starch and body, feeding the yeast and thickening the starter.
- Sugar
- Gives the yeast an easily used food source to speed up fermentation.
- Coarse sea salt
- Controls yeast activity so fermentation proceeds steadily rather than too fast.
The step that matters
Cover and let rise overnight. The starter needs a long, undisturbed fermentation for the yeast to multiply and develop flavor. Covering it keeps the surface from drying and crusting, which would stop the rise.
