Why it works: Potato and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bread
Ingredients
Directions
Make the hop water and potatoes
Boil hops in 1 quart of water in a small bag.
Peel and add potatoes to the boiling water.
Once potatoes are soft, pass them through a colander, moistening with some hot water.
Squeeze the bag of hops and return the pulp to the water.
Stir the mixture and bring it just to a boil.
Make the batter and sponge
Pour the hot mixture over enough flour to make a thin batter.
When the batter is tepid, add 1 pint of yeast.
Store in a crock with a lid in a cool place until evening.
Make the dough and rolls
For dry yeast, boil 1 pint of hops in 1 quart of water, strain hot over 1 pint of flour and 1 tablespoon of salt.
Stir well and let cool, then add enough Indian meal to make a stiff dough.
Roll into rolls and let rise until light.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down into a starchy mash that adds body and moisture to the dough.
- Flour
- Forms the batter and then the dough's structure as it absorbs liquid and sets.
- Yeast
- Ferments the sugars and produces gas that makes the dough rise.
- Hops
- Contribute bitterness and aroma, and their natural preservative qualities help the brew keep.
- Indian meal
- Stiffens the dough and adds coarser texture to the rolls.
The step that matters
When the batter is tepid, add the yeast. Yeast is killed by very hot liquid but works slowly in cold, so the batter must cool to lukewarm before yeast is added for steady fermentation and rising.
Swap the potato
How well each one fits the dish's main ingredients (hops, flour):
- Mustardfits better
- Arrowrootfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against hops, flour. Candidates are from the same food group and used in at least 100 recipes.
