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.
Prepare the sauce
Separate the whites from the yolks of the hard-boiled eggs and chop them finely.
In a saucepan, melt the butter over medium heat, then stir in the flour and cook until smooth.
Gradually add the sweet milk, stirring until the sauce thickens. Season with salt and pepper.
Assemble and bake
Butter a baking dish and spread a layer of sauce on the bottom.
Layer the ground ham, chopped yolks, and chopped whites in the dish, then top with the remaining sauce.
Sprinkle fine cracker crumbs and small pieces of butter on top.
Bake in a preheated oven at 350 °F (175 °C) for about 30 minutes, or until brown.

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, on top, helps the crumbs brown in the oven.
- Sweet milk
- Forms the liquid base of the sauce, which sets as it thickens and bakes.
- Hard boiled eggs
- Add body and richness to the layers as their yolks and whites set when baked.
- Boiled ham
- Supplies the savory meat flavor and substance of the casserole.
The step that matters
Thickening the sauce. Flour must be cooked in the melted butter until smooth before the milk is added, and the milk stirred in gradually, so lumps do not form and the sauce thickens evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
