Georgia Sweet Potato Biscuit

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Bake the sweet potatoes and run them through a meat grinder before measuring.

  2. In a bowl, mix the mashed sweet potatoes with flour and sugar.

  3. Rub in the lard, then add baking soda and enough buttermilk to form a good biscuit dough.

  4. Allow the dough to stand for several hours.

Bake

  1. Mold the dough into biscuits and bake in a moderate oven at 350°F (175°C) until golden.

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

What each ingredient does

All-purpose flour
Provides the structure that holds the biscuit together.
Lard
Rubbed into the flour to add tenderness and a flaky texture.
Mashed sweet potato
Adds moisture and body, and a soft, tender crumb.
Baking soda
Reacts with the acidity to help the biscuits rise.
Sugar
Adds sweetness and helps the biscuits brown in the oven.
Buttermilk
Moistens the dough and its acidity activates the baking soda.

The step that matters

Rubbing in the lard. Lard should be worked into the flour until it is evenly broken up. Pockets of fat melt in the oven and create flaky layers, while overworking the dough develops gluten and makes the biscuits tough.

Swap the sweet potato

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

  1. Arrowrootfits better
  2. Chivefits about as well
  3. Sweet potatothe original
  4. Beetrootfits about as well

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