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 liquor
Boil 1 handful of hops in a bag with 1 quart of water.
Squeeze the bag of hops and return the pulp to the water.
Stir the mixture and bring it to a boil.
Make the potato batter
Peel and add 6 large potatoes to the boiling water until soft.
Pass the potatoes through a colander, moistening with some hot water.
Pour the hot mixture over sufficient flour to make a thin batter.
When tepid, add ½ pint of yeast and mix well.
Rest
Place in a crock with a lid in a cool place for use in the evening if made in the morning.

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
- Mashed into the batter, they add body, moisture and starch that feeds the yeast.
- Yeast
- Ferments the batter so the bread rises and gains its airy texture.
- Flour
- Forms the structure of the batter, setting as it cooks and dries.
- Hops
- Add bitterness and aroma, and their natural preservative character helps the batter keep.
The step that matters
Adding the yeast when tepid. Yeast is killed by high heat, so the mixture must cool to lukewarm before adding it. If it is still hot, the yeast will not ferment and the bread will not rise.
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.
