Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Scalloped Asparagus
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 hot, salted water for 10 minutes.
Drain and layer the asparagus in a buttered baking dish.
Make the sauce and layer
Scatter minced hard-boiled eggs over the asparagus and season with salt, pepper, and bits of butter.
Repeat layering until all ingredients are used.
Make a roux with 1 tablespoon of butter and 1 tablespoon of flour, then thin with 1 cup of hot milk.
Cook for 1 minute, season with paprika, and pour over the asparagus.
Bake and serve
Top with a final layer of asparagus, sprinkle with fine bread crumbs, and add bits of butter and grated cheese.
Bake covered at 350°F (175°C) for 20 minutes, 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 bulk of the dish and gives its tender, vegetable texture.
- Hard-boiled eggs
- Adds soft, rich body and mild flavor between the asparagus layers.
- Butter
- Adds richness and flavor, and helps the top brown during baking.
- Flour
- Thickens the butter and milk into a smooth sauce as a roux.
- Milk
- Forms the liquid base of the sauce that moistens the dish.
- Grated cheese
- Melts into the top layer and adds savory flavor and browning.
The step that matters
Thinning the roux with hot milk. Adding the milk to a roux while it is cooked and smooth helps prevent lumps. Cooking the mixture briefly removes raw flour taste and lets the sauce thicken evenly.
