Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Prepare

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

Make the batter

  1. In a bowl, combine mashed potato, melted butter, beaten egg, milk, and salt, and mix until smooth and well combined.

  2. Pour the mixture into a buttered baking pan.

Bake

  1. Bake in the preheated oven until golden brown.

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

What each ingredient does

Eggs
Bind the mixture and help it set into a puffed, sliceable structure as it bakes.
Mashed potato
Provides the bulk and body of the puff, giving it a soft, tender texture.
Milk
Adds moisture and loosens the mixture so it spreads and bakes evenly.
Butter
Adds richness and fat, contributing flavor and helping the surface brown.

The step that matters

Bake until golden brown. Baking long enough sets the egg and starch so the puff holds its shape, while stopping at golden brown avoids drying it out or burning the surface.

Swap the potato

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

  1. Potatothe original
  2. Asparagusfits about as well
  3. Chivefits less well
  4. Leekfits less well

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