Omelet Souffle

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. Preheat the oven to 350°F (175°C).

  2. Whip the egg whites with a pinch of salt until stiff peaks form.

  3. Beat the egg yolks and powdered sugar until creamy, then add the lemon zest and juice.

  4. Gently fold the whipped egg whites into the yolk mixture without stirring.

Bake and serve

  1. Pour the mixture into a lightly oiled pudding dish.

  2. Optionally, shape part of the mixture into a mound on a flat dish and pipe the rest on top.

  3. Sprinkle with sugar and bake until set.

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

What each ingredient does

Egg whites
Whipped into stiff peaks, they trap air and give the soufflé its light, risen structure.
Egg yolks
Enrich the batter with richness and help it set into a tender, custard-like texture.
Powdered sugar
Sweetens the batter and dissolves easily into the yolks for a smooth base.
Lemon zest
Adds aromatic lemon oil that brightens the flavour of the batter.
Lemon juice
Adds acidity that balances the sweetness and sharpens the lemon flavour.

The step that matters

Gently fold the whipped egg whites into the yolk mixture. Whipped egg whites hold air in a fragile foam. Stirring or overmixing deflates it, so the soufflé rises less and turns dense. Fold with a light, sweeping motion to keep the air in.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits about as well
  3. Lemonthe original
  4. Datesfits less well

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