Duchess 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 the potatoes

  1. Boil the potatoes until tender, then drain them.

  2. Add butter, eggs, white pepper, and salt to the potatoes.

  3. Mash and press the mixture through a sieve.

Shape and bake

  1. Form the mixture into small oval loaves, flat on top.

  2. Mark the tops with a knife and brush with melted butter.

  3. Bake in a preheated oven at 400°F (200°C) 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

Potatoes
Form the bulk of the dish and set its soft, fluffy body once mashed.
Butter
Adds richness and moisture, and the melted layer on top helps the surface brown.
Eggs
Bind the mashed potato so the shaped loaves hold their form and set when baked.

The step that matters

Pressing the mixture through a sieve. Mashing alone leaves lumps and uneven texture. Pressing the mash through a sieve breaks up remaining fibers and lumps, giving the smooth, piping-ready consistency the shaped loaves need to hold their outline.

Swap the white pepper

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

  1. Parsleyfits better
  2. Nutmegfits better
  3. Capersfits better
  4. White pepperthe original

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