  5. Let the mixture cool to blood-warm, then add 1 cup of yeast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Supply starch and moisture that feed the yeast and give the mixture body.
Yeast
Ferments the sugars and produces gas, making the mixture rise.
Sugar
Provides food for the yeast, speeding fermentation and adding mild sweetness.
Hops
Adds bitterness and aroma and helps preserve the liquid.

The step that matters

Cool to blood-warm before adding the yeast. Yeast is killed by very hot liquid, so the mixture must cool to about body temperature before the yeast goes in. Too hot and it will not rise; the warm rise that follows then depends on live yeast working in gentle heat.

Swap the potato

How well each one fits the dish's main ingredients (hops, sugar):

  1. Mustardfits better
  2. Cucumberfits about as well
  3. Capsicumfits about as well
  4. Potatothe original

Fit is the average pairing score against hops, sugar. Candidates are from the same food group and used in at least 100 recipes.
