Why it works: Asparagus and biscuit share more aroma than cooks usually use. They rank in the top 7% of all ingredient pairs, and cooks put them together in 25 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ambushed Asparagus
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
Cut off the tender tops of the asparagus.
Boil the asparagus until tender, then drain.
Cut the tops off the biscuits or rolls. Scoop out the insides of the biscuits or rolls.
Place the biscuits in a 400°F (200°C) oven to crisp, along with the tops.
Make the custard
Heat the milk in a saucepan until boiling. Beat the eggs into the boiling milk.
Stir the mixture over heat until it thickens.
Add the butter, salt, and pepper to the mixture.
Mix the asparagus into the custard without boiling.
Assemble and serve
Fill the prepared biscuits with the asparagus custard.
Replace the tops on the biscuits.
Return the biscuits to the oven for 3 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook and thicken it into a spoonable filling.
- Milk
- Forms the liquid base of the custard, carrying the eggs and setting gently with heat.
- Asparagus
- Provides the main vegetable flavour and tender texture within the custard.
- Biscuits or rolls
- Act as the edible shell that holds the custard and crisps in the oven.
- Butter
- Adds richness and a smooth, silky mouthfeel to the custard.
The step that matters
Beat the eggs into the boiling milk. Egg proteins set when heated, so over-high heat or too rapid mixing can scramble the custard. Keep the mixture hot but controlled, then stir until it thickens, and do not let the asparagus custard boil once combined.
