Why it works: Milk and butter 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 ↓
Asparagus in Ambush
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Chop and season the asparagus.
Cut off the tops of the rolls and scrape out the insides.
Place the rolls in the oven to crisp.
Make the filling
In a saucepan, stir the beaten eggs and milk over low heat until thickened.
Add the butter rolled in flour to the mixture.
Stir in the chopped asparagus.
Fill and serve
Fill the rolls with the asparagus mixture, replace the tops, and serve hot.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs set as they heat, thickening the milk into a custard-like filling.
- Milk
- Provides liquid that combines with the eggs to form a creamy, tender filling.
- Flour
- Rolled into the butter, it thickens the mixture as it heats.
- Butter
- Adds fat and richness, giving the filling a smoother, silkier texture.
- Asparagus
- Supplies the main flavor and texture of the filling.
The step that matters
Stir the eggs and milk over low heat until thickened. Egg proteins set at moderate temperatures, so heating gently while stirring keeps the mixture smooth. High heat can scramble the eggs into lumps.
