Why it works: Bread and butter 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 in Ambush
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the asparagus
Wash the asparagus tips.
Boil the asparagus tips in salted water for 15 minutes.
Drain the asparagus tips in a colander.
Make the bread boxes
Cut the bread into 1.5‑inch thick slices.
Remove the crusts from the bread slices.
Hollow out the center of each slice to form a box.
Brush the outside of the bread boxes with melted butter.
Bake the bread boxes in a 400°F (200°C) oven until golden brown.
Make the sauce and serve
Fill the centers of the bread boxes with the drained asparagus tips.
Keep the filled bread boxes warm.
Heat the milk in a double boiler.
Beat the egg yolks until light.
Stir the beaten yolks into the hot milk until it begins to thicken.
Remove the sauce from the heat.
Add butter, salt, and pepper to the sauce.
Pour the sauce into the bread boxes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tips
- Provide the main vegetable filling and a tender, green texture.
- Bread
- Forms a sturdy, crisp box that holds the filling and sauce.
- Milk
- Forms the base of the sauce, which thickens when heated with the yolks.
- Egg yolks
- Thicken the hot milk into a smooth, creamy sauce as they set.
- Butter
- Browns the bread boxes and adds richness to the finished sauce.
The step that matters
Stir the beaten yolks into the hot milk until it begins to thicken. Egg yolks set when heated, so they can curdle or scramble if the milk is too hot or added too fast. Removing the sauce from the heat as it thickens keeps it smooth.
