Potatoes Scalloped with Eggs

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 potatoes

  1. Beat the hot mashed potatoes smooth with milk, butter, and the beaten raw egg.

  2. Season well with salt and pepper.

Layer and bake

  1. Layer half of the potato mixture in a buttered baking dish.

  2. Add a layer of sliced hard-boiled egg yolks, seasoned with salt and pepper.

  3. Repeat the layers, finishing with potatoes on top.

  4. Strew the top with fine crumbs.

  5. Cover the dish.

  6. Bake at 350°F (175°C) for 30 minutes.

  7. Remove the cover.

  8. Bake until browned.

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

What each ingredient does

Mashed potatoes
Forms the bulk of the dish and gives a soft, creamy body.
Beaten raw egg
Binds the potatoes and sets during baking to hold the layers together.
Hard-boiled egg yolks
Add a rich, crumbly texture and savory flavor between the potato layers.
Butter
Adds fat for richness and helps the top brown during uncovered baking.
Milk
Adds moisture so the mashed potatoes beat into a smooth, spreadable mixture.

The step that matters

Remove the cover before the final bake. Covering keeps steam in so the potatoes heat through without drying. Uncovering lets surface moisture evaporate, which allows the crumbs and potato top to brown.

Swap the potato

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

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

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