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

What each ingredient does

Potatoes
Provide starch and moisture that feed the yeast and keep the dough soft.
Common yeast
Produces gas that makes the dough rise and gives the bread its airy crumb.
Flour
Forms the gluten network that gives the dough structure and holds the risen gas.
Honey
Gives the yeast quick sugar to feed on, aiding fermentation and adding mild sweetness.

The step that matters

Make the bread as soon as the mixture begins to fall. Once the starter has peaked and begins to collapse, yeast activity is waning and gas production is slowing. Baking at this point, rather than later, captures the most lift before the dough over-ferments and turns sour and flat.

Swap the potato

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

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

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