Why it works: Butter and bread match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,145 recipes mention both. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: egg
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).
Assemble and bake
Layer sliced hard-boiled eggs in a buttered casserole, alternating with bread crumbs until the dish is filled.
Pour hot milk mixed with melted butter over the layers.
Cover with bread crumbs moistened in melted butter.
Bake until hot.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs (in the method)
- Form the main body of the dish, setting into a tender, sliceable structure as they heat.
- Milk
- Provides the liquid that moistens the layers and sets gently into a creamy custard.
- Bread crumbs
- Absorb the milk and butter, giving the layers body and a toasted top.
- Butter
- Adds richness and carries flavor, helping the crumb topping brown.
The step that matters
Pour the hot milk over the layers. Hot milk soaks into the crumbs and begins setting the egg custard evenly. Cold milk would slow the heating and leave the dish uneven when baked.
