Oven, in the book's wordsA hot oven

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.

Prepare

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

  2. Fold the stiffly beaten egg whites into the hot seasoned mashed potatoes.

  3. Turn the mixture into well-buttered individual dishes or one large flat dish.

Bake and serve

  1. Bake in the hot oven for 15 minutes until browned.

  2. Serve immediately with fish, meat, or entrees.

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

Egg whites
Whipped into foam, they lighten the potatoes and give the soufflé its rise and airy texture.
Mashed potatoes
Form the body of the soufflé, giving it a soft, moist interior that holds the whipped whites.

The step that matters

Folding the egg whites into the potatoes. Stirring too hard deflates the whipped egg whites, releasing the air bubbles that make the soufflé rise. Fold gently, cutting through the mixture and turning it over, so the batter stays light.

Swap the potato

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

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

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