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 ↓
Asparagus Au Gratin
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
Boil the asparagus until tender, then drain.
Assemble
In a bowl, mix the asparagus with melted butter, bread crumbs, salt, pepper, cream, grated cheese, and egg white.
Fill buttered shells or individual ramekins with the mixture.
Bake
Bake at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Binds the mixture together and helps it set when baked.
- Bread crumbs
- Absorb liquid and add body, giving the topping a light texture.
- Cream
- Adds moisture and richness so the mixture stays tender when baked.
- Grated cheese
- Melts and browns on top, adding flavor and a golden crust.
- Melted butter
- Adds fat for richness and helps the crumbs brown evenly.
The step that matters
Bake until golden brown. Baking long enough to brown the top sets the egg white and firms the custard-like mixture, while over-baking can dry it out and make it rubbery.
