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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hops
- Adds bitterness and aroma to the hop liquor.
- Potatoes
- Provide starch and body to the liquid mixture.
- Indian meal
- Thickens the mixture and adds body as it boils.
- Flour
- Adds starch that thickens the mixture as it boils.
- Yeast
- Ferments the sugars, producing carbonation and flavor.
The step that matters
Let it cool until milk warm before adding the yeast. Yeast is killed by excessive heat. Cooling the mixture to milk warm lets the yeast stay active so it can ferment the sugars and carbonate the liquid.
Swap the potato
How well each one fits the dish's main ingredients (hops, flour, sugar):
- Mustardfits better
- Arrowrootfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against hops, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
