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 ↓
Dry Yeast Cakes
Ingredients
Directions
Prepare the starter
Place the hops and sliced potatoes in a quart of water and boil until the potatoes are soft.
In a bowl, combine the flour, sugar, and salt.
Scald the flour mixture with the hop and potato water, mashing until smooth.
Make the dough
Once cool, add 4 soaked yeast cakes and let it rise until lively.
Stir in cornmeal until the mixture is stiff enough to cut into cakes.
Dry the cakes
Dust a board with cornmeal and spread the cakes on it, turning frequently until dry.
In warm weather, dry the cakes in the air, avoiding direct sunlight; in cold weather, dry them in a warm room near the stove.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the body of the dough, and when scalded it thickens and sets the structure.
- Yeast cakes (in the method)
- Ferment the mixture so it rises and becomes light and lively.
- Potatoes
- Add starch and moisture that help the dough hold together and stay soft.
- Hops
- Add a bitter, aromatic flavour and help preserve the liquid.
- Sugar
- Feeds the yeast and adds sweetness to the cakes.
The step that matters
Scalding the flour mixture. Pouring the hot liquid over the flour and mashing it until smooth cooks the starch so it gelatinizes and thickens, and removes lumps. Under-heated or lumpy flour gives a dense, uneven dough.
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.
