Potato Puff

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.

Make the mixture

  1. In a skillet, combine cold mashed potatoes, egg yolks, butter, cream, salt, and pepper.

  2. Stir the mixture until it is very hot.

  3. Remove from heat and gently fold in the beaten egg whites.

Bake

  1. Transfer the mixture to a baking dish and bake in a 400°F (200°C) oven until browned.

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

What each ingredient does

Potatoes
Provide the bulk and soft, moist body of the puff.
Egg yolks
Add richness and help bind the mixture together.
Butter
Adds fat for richer flavour and a tender texture.
Cream
Adds moisture and smoothness to the potato base.

The step that matters

Fold in the beaten egg whites gently, off the heat. Beaten egg whites trap air that helps the puff rise and stay light. Vigorous stirring deflates them, and heat can start setting the proteins too early, so folding gently and off the heat keeps the mixture airy.

Swap the potato

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

  1. Potatothe original
  2. Spinachfits about as well
  3. Asparagusfits about as well
  4. Capsicumfits about as well

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