Scalloped 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

Preheat the oven to 350°F (175°C).
In a well-buttered dish, place a layer of bread or cracker crumbs.

Layer and add milk

Add a layer of sliced hard-boiled eggs, bits of butter, pepper, and salt.
Repeat layers until the dish is full, finishing with crumbs on top.
Pour 1 cup of milk over the entire dish.

Bake

Bake in the oven until browned nicely.

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

What each ingredient does

Hard-boiled eggs: Provide the main body of the dish, setting into a soft, sliceable structure as they heat.
Bread or cracker crumbs: Soak up the milk and give the layers structure, then brown on top.
Milk: Supplies moisture that sets gently around the eggs and crumbs during baking.
Butter: Adds richness and helps the top crumbs brown.
