Baked Potatoes

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

  1. Preheat the oven to 400 °F (200 °C).

  2. Wash and dry the potatoes.

Bake and fill

  1. Bake the potatoes until tender.

  2. Cut each potato in half lengthwise and scoop out the insides.

  3. Mash the potato insides with butter and coarse sea salt.

  4. Mix the beaten egg white into one half of the mashed potato.

Finish

  1. Return the mashed potato to the skins and bake again until golden.

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

Potatoes
Provide the starchy interior that becomes fluffy when baked and mashed.
Butter
Adds fat for richness and a smoother, softer mashed texture.
Beaten egg white
Sets when heated, helping the mashed filling hold its shape and brown.

The step that matters

Bake again until golden. The second bake sets the egg white and browns the filling. Baking too long dries the mash, so watch the colour rather than only the clock.

Swap the potato

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

  1. Asparagusfits better
  2. Chivefits better
  3. Leekfits about as well
  4. 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.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
