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):

  1. Mustardfits better
  2. Arrowrootfits better
  3. Parsnipfits better
  4. 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.
