Why it works: Potato and ginger work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 992 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Home Made Yeast Cakes
Ingredients
Directions
Make the mixture
Boil hops and potatoes in 3 pints of water until done.
Mash the potatoes smoothly and mix with 1 pint of flour.
Pour the boiling hop water over the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast cake
- Ferments the mixture, producing gas that makes the cakes rise and become light.
- Potatoes
- Add starch and body, giving the cakes a soft, moist crumb.
- Flour
- Mixes with the mashed potato to form the base structure of the dough.
- Sugar
- Feeds the yeast and adds a little sweetness.
- Hops
- Contribute bitterness and aroma, and help preserve the mixture.
The step that matters
Let the mixture cool to lukewarm before adding the yeast. Yeast is killed by very hot liquid. Cooling the mixture to lukewarm keeps the yeast alive so it can ferment and leaven the cakes.
Swap the potato
How well each one fits the dish's main ingredients (hops, flour, sugar, ginger):
- Mustardfits better
- Arrowrootfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against hops, flour, sugar, ginger. Candidates are from the same food group and used in at least 100 recipes.
