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 ↓
Potato and Hop Yeast
Ingredients
Directions
Prepare the potato mixture
Boil the potatoes in boiling water until the skins crack, adding the hops tied in a muslin cloth after the potatoes are in.
Mash the potatoes with the skins on.
Pour the boiled water over the mashed potatoes.
Add 2 tablespoons of flour.
Add the yeast
Dissolve the yeast in warm water and add it to the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch that gives the bread body and moisture, and feeds the yeast.
- Yeast
- Produces gas that makes the bread rise.
- Flour
- Adds structure to the mixture as it thickens.
- Compressed hops
- Adds bitter and aromatic flavor to the bread.
The step that matters
Dissolve the yeast in warm water. Yeast works best in warm, not hot, liquid. Water that is too hot can kill yeast cells, so the bread may fail to 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.
