Sweet Potato Biscuit

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 the sweet potatoes until tender, then mash them.

  2. Mix in the butter and salt until well combined.

  3. Form the mixture into round, flat biscuits.

Coat and bake

  1. Dip each biscuit in the beaten egg.

  2. Coat each biscuit with cracker crumbs.

  3. Dip each biscuit in the beaten egg again.

  4. Place the biscuits on a baking sheet.

  5. Bake in a 400°F (200°C) oven until browned.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Sweet potatoes
Provide the main bulk and moisture, giving the biscuits a soft, tender interior.
Butter
Adds fat for richness and a tender texture.
Egg
Binds the coating so the cracker crumbs stick to each biscuit.
Cracker crumbs
Form a crisp outer crust that browns in the oven.

The step that matters

Coat and re-dip in egg. The egg must be set on each biscuit before crumbs go on, so the coating sticks evenly. Double-dipping builds a thicker, more even crust that browns well in the oven.

Swap the sweet potato

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

  1. Asparagusfits better
  2. Chivefits better
  3. Leekfits better
  4. Sweet potatothe original

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