Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Potato Yeast
Ingredients
Directions
Make the potato base
Peel the potatoes and place them in a saucepan. Cover with water.
Boil until perfectly soft, then remove the potatoes, leaving the water on the heat.
Mash the potatoes smooth with the flour and sugar, then gradually stir in the quart of water.
Let this mixture boil, then strain it through a colander.
Add yeast and store
When lukewarm, stir in the dissolved yeast.
Let it rise until light, then store in the refrigerator or a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Their starch and dissolved solids thicken the liquid and feed the yeast.
- Yeast
- Its fermentation makes the mixture rise and turns it light and active.
- Flour
- Thickens the mashed potato mixture so it holds together as a starter.
- Sugar
- Gives the yeast an easily used food source to drive fermentation.
The step that matters
Stir in the yeast when lukewarm. Yeast is killed by very hot liquid, so the mixture must have cooled to lukewarm before the yeast goes in. Too hot and the yeast will not activate and the starter will fail to rise.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
