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 ↓
Scalloped Aspaeagus
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 asparagus
Wash the asparagus and cut off the hard, woody parts of the stalks.
Cut the tender parts into 1‑inch lengths and parboil in salted water for 10 minutes.
Drain and layer the asparagus in a buttered baking dish.
Layer and sauce
Scatter minced hard‑boiled eggs over the asparagus and season with salt, pepper, and bits of butter.
Repeat layering until all ingredients are used.
In a saucepan, melt 2 tablespoons of butter and stir in 1 tablespoon of flour to make a roux.
Thin the roux with 1 cup of hot milk and cook for 1 minute, seasoning with paprika.
Pour the sauce over the asparagus, ensuring a layer is on top.
Top and bake
Sift breadcrumbs over the dish and dot with butter, then sprinkle with grated cheese.
Bake at 350°F (175°C) for 20 minutes, covered, then uncover and brown slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main body of the dish and gives it its vegetable flavor and tender texture.
- Hard-boiled eggs
- Add richness and a soft, binding texture between the asparagus layers.
- Butter
- Adds richness and fat, helping the sauce coat the layers and the topping brown.
- All-purpose flour
- Thickens the butter and milk into a smooth white sauce through the roux.
- Milk
- Forms the liquid base of the sauce, giving it a creamy, soft body.
- Fine breadcrumbs
- Form a crisp, golden topping that adds texture over the baked dish.
The step that matters
Thinning the roux with hot milk. Adding cold milk to a hot roux can cause lumps, while cooking the sauce briefly after thinning removes the raw flour taste and lets it thicken smoothly.
