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 wort
Pour boiling water over hops and strain it onto the grated potatoes.
Let the mixture sit until it is warm to the touch.
Ferment and bottle
Add yeast and 2 quarts of boiling water to the mixture.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch that yeast can convert into sugar and alcohol during fermentation.
- Yeast
- Ferments the sugars, producing alcohol and carbon dioxide that carbonates the beer.
- Sugar
- Supplies readily fermentable sugar that feeds the yeast and adds sweetness.
- Hops
- Add bitterness and aroma that balance the sweetness of the potato mixture.
The step that matters
Bottle and cork tightly. Fermentation keeps producing carbon dioxide after bottling. A loose cork lets gas escape, so the beer goes flat, and a tight seal lets pressure build for natural carbonation.
Swap the potato
How well each one fits the dish's main ingredients (hops, sugar):
- Mustardfits better
- Cucumberfits about as well
- Capsicumfits about as well
- Potatothe original
Fit is the average pairing score against hops, sugar. Candidates are from the same food group and used in at least 100 recipes.
