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

What each ingredient does

Hops
Gives the liquid a bitter, aromatic flavour.
Potatoes
Add starch and body, thickening the liquid and giving the bread a soft texture.
Flour
Thickens the boiled mixture and adds starch for the yeast to work on.
Sugar
Provides food for the yeast and adds a little sweetness.
Yeast
Ferments sugars and releases carbon dioxide, which makes the dough rise.

The step that matters

Add the yeast when nearly cold. Yeast cells are damaged or killed by high heat. Adding yeast to a mixture that is still hot can stop fermentation, so the mixture should cool to near room temperature first.

Swap the potato

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

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

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