Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Bake the potatoes

  1. Bake the sweet potatoes until tender.

Prepare the filling

  1. Cut them lengthwise and scoop out the insides.

  2. Mash the insides and season with salt and pepper.

  3. Fold in the beaten egg white.

Refill and bake

  1. Refill the potato skins with the mixture.

  2. Bake for 5 minutes in a hot oven at 400°F (200°C).

Recipe from a historical cookbook (Internet Archive).

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 bulk of the filling and its soft, starchy texture once baked and mashed.
Egg white
Adds structure and helps the filling hold together and rise slightly when baked.

The step that matters

Fold in the beaten egg white. Folding gently keeps air in the beaten egg white, which helps the filling stay light. Stirring vigorously deflates it and can make the filling dense.

Swap the sweet potato

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

  1. Capsicumfits better
  2. Spinachfits better
  3. Asparagusfits better
  4. Sweet potatothe original

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