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 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.
Cut off the hard, woody parts.
Cut the tender parts into 1‑inch lengths.
Par‑boil the asparagus in hot, salted water for 10 minutes.
Drain the asparagus.
Layer the dish
Butter a baking dish.
Layer the asparagus in the dish.
Scatter minced hard‑boiled eggs on top.
Season with salt, pepper, and bits of butter.
Repeat layering until all ingredients are used.
Make the sauce
Make a roux with 2 tablespoons butter and 1 tablespoon flour.
Thin the roux with 1 cup hot milk.
Cook the sauce for 1 minute.
Season the sauce with paprika.
Pour the sauce over the top layer of asparagus.
Bake and brown
Sift breadcrumbs over the dish.
Add bits of butter.
Sprinkle grated cheese.
Bake covered at 350°F (175°C) for 20 minutes.
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 texture and flavour.
- Hard-boiled eggs
- Add a firm, rich texture and body between the asparagus layers.
- Butter
- Enriches the roux and adds fat and flavour to the sauce and top layers.
- Flour
- Thickens the milk into a smooth sauce when cooked with butter as a roux.
- Milk
- Forms the liquid base of the sauce, giving it creaminess once thickened.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
The step that matters
Thin the roux with hot milk. Adding the milk gradually while stirring keeps the flour smooth and lump-free. Cooking the sauce briefly afterwards lets the starch thicken fully and loses the raw flour taste.
Swap the asparagus
How well each one fits the dish's main ingredients (egg, pepper, butter, flour, milk, cheese):
