Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Ham Scallop
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.
Make the sauce
In a saucepan, melt 2 tablespoons of butter over medium heat.
Stir in 4 tablespoons of flour and cook until smooth.
Gradually add 1 pint of sweet milk, stirring until thickened.
Season the sauce with salt and pepper.
Assemble and bake
Butter a baking dish and layer the sauce, followed by the ground ham, sliced eggs, and another layer of sauce.
Top with fine cracker crumbs and small pieces of butter.
Bake at 350°F (175°C) for about 30 minutes, or until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a smooth white sauce that holds the layers together.
- Butter
- Enriches the sauce and, as small pieces on top, helps the crumbs brown.
- Boiled ham
- Provides the savory, meaty filling layer.
- Hard-boiled eggs
- Add richness and a soft, creamy texture to the layers.
- Sweet milk
- Forms the liquid base of the sauce, which thickens as it heats with the flour.
The step that matters
Thickening the sauce. Add the milk gradually while stirring so the flour disperses evenly; adding it all at once can leave lumps, and the sauce must thicken before layering so the casserole sets rather than runs.
