  5. Let stand in a warm place for 18 hours.

Make the dough

  1. Take 2 cups of the mixture for each loaf.

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

What each ingredient does

Flour
Forms the bulk of the starter, giving the mixture body and structure for the dough.
Potatoes
Their cooking water and starch add moisture and food for the yeast.
Yeast cakes
Ferment the starter, producing gas that makes the dough rise.
Sugar
Feeds the yeast during fermentation and contributes sweetness.
Lard
Adds fat that tenderizes the dough and softens its texture.

The step that matters

Knead just enough to make the dough smooth, but not too stiff.. Kneading develops gluten for structure, but overworking or adding too much stiffness makes the dough tough and dense. Stopping once it is smooth keeps the crumb light and the dough workable.

Swap the potato

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

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

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