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.

Make the dough

Boil and mash the sweet potatoes.
Mix in enough flour to form a dough similar to bread.
Add nutmeg and sugar to taste.
Stir in the yeast and let the mixture rise.
Work in the butter until well combined.

Shape and bake

Form the dough into small rolls.
Bake on a baking sheet at 400°F (200°C) until golden brown.

Serve

Serve hot, break open, and butter.

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

What each ingredient does

Sweet potatoes: Provide moisture and body, giving the dough a soft, tender crumb.
Flour: Forms the gluten structure that gives the dough its bread-like shape and chew.
Active dry yeast: Produces gas as it ferments, making the dough rise and become light.
Butter: Adds fat that tenderizes the crumb and enriches the flavour.
Sugar: Sweetens the buns and feeds the yeast, helping browning in the oven.

The step that matters

Let the mixture rise. The yeast needs enough time to ferment and build gas, so the buns rise and turn light. Under-proofed dough stays dense and heavy after baking.
