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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch and body that gives the brew its substance and mouthfeel.
- Hops
- Add bitterness and aroma that balance the sweetness of the brew.
- Sugar
- Feeds the yeast, supplying the fermentable sugar that produces alcohol and carbonation.
- Yeast
- Ferments the sugars into alcohol and carbon dioxide, turning the liquid into beer.
The step that matters
Stir in the yeast before the liquid cools. Yeast works best at lukewarm temperatures. If the liquid is too hot it can kill the yeast, and if it cools too far fermentation may be slow to start. Adding the yeast while the mixture is still warm but not hot gives it a good start.
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.
