Potato Omelet

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

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

Make the batter

  1. In a bowl, combine the mashed potatoes, yolks of the eggs, flour, and milk.

  2. In a separate bowl, beat the egg whites until stiff peaks form.

  3. Gently fold the beaten egg whites into the potato mixture.

Bake and serve

  1. Pour the mixture into a well-greased saucepan.

  2. Bake until set and lightly golden, then serve hot.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Whites beaten to stiff peaks trap air, lifting the omelet, while yolks add richness and set the custard.
Mashed potatoes
Provide bulk and moisture, giving the omelet a soft, tender body.
Flour
Helps the mixture hold together and gives it a more stable structure when baked.
Milk
Adds moisture and softness to the batter.

The step that matters

Folding the beaten egg whites into the potato mixture. Folding gently keeps the air bubbles in the whites intact. Stirring or deflating them loses the lift that makes the omelet light.

Swap the parsley

The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, egg, flour, milk):

  1. Nutmegfits better
  2. Cinnamonfits about as well
  3. Dillfits about as well
  4. Parsleythe original

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