Sweet Potato Buns

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Boil and mash the sweet potato.

  2. Mix in enough flour to form a dough.

  3. Add spice and sugar to taste, along with the yeast.

  4. Let the dough rise until doubled in size.

  5. Work in the butter.

Shape and bake

  1. Shape into small rolls and bake at 400°F (200°C) until golden.

  2. Serve hot with butter.

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

What each ingredient does

Sweet potato
Adds moisture and soft, tender crumb to the dough.
Flour
Forms the gluten structure that gives the buns their body.
Yeast
Produces gas as it ferments, making the dough rise and become airy.
Butter
Adds fat that tenderizes the crumb and enriches flavor.
Sugar
Feeds the yeast and adds sweetness and help with browning.

The step that matters

Let the dough rise until doubled in size. Yeast needs enough time to produce gas and develop flavor. Underproofed dough bakes up dense, while overproofed dough can collapse or lose structure.

Swap the sweet potato

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

  1. Arrowrootfits about as well
  2. Shallotfits about as well
  3. Sweet potatothe original
  4. Leekfits about as well

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