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

Potatoes
Add moisture and starch that give the bread a soft, moist crumb.
Flour
Forms the gluten network that gives the dough its structure and chew.
Yeast
Produces gas as it ferments, causing the dough to rise and turn light.
Sugar
Feeds the yeast and helps the crust brown during baking.
Butter
Adds fat that tenderizes the crumb and carries flavor.

The step that matters

Waiting until the dough is light before shaping. Yeast needs time to produce gas and build structure. Shaping or baking too early gives dense loaves, while a fully risen dough holds its shape and bakes up airy.

Swap the potato

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

  1. Arrowrootfits better
  2. Shallotfits better
  3. Sweet potatofits better
  4. Potatothe original

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