The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Old potatoes
Mashed potato adds body and moisture to the dough, helping it hold together.
Hops
Boiled hop water gives the bread a bitter, aromatic flavour.
Flour
Forms the structure of the dough that holds the bread together.
Baker's yeast
Ferments the dough so it rises and becomes light.

The step that matters

Stir in the yeast after the mixture cools. Yeast is killed by very hot liquid, so the mixture must cool before the yeast is added, or it will fail to leaven the dough.

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.
