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).
Cut the hard-boiled eggs in half and remove the yolks.

Make the filling

Mash the yolks finely and mix in the butter, powdered crackers, milk, pepper, and salt.

Bake

Place the egg whites in a baking dish and pour the yolk mixture over them.
Bake for 15 minutes.

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

What each ingredient does

Hard-boiled eggs: Egg whites form the base and yolks become the creamy filling.
Butter: Adds richness and fat that makes the mashed yolk filling smooth.
Powdered crackers: Absorb liquid and give the filling body and a light, savory texture.
Milk: Adds moisture so the mashed yolk mixture spreads and stays soft when baked.
