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 ↓
Asparagus -in Ambush
Ingredients
Directions
Prepare the rolls
Remove the crumb from the rolls and cut off the tops to serve as covers.
Set the rolls open in the oven to crisp, laying the tops beside them.
Make the filling
Heat the milk and pour it over the beaten eggs.
Stir over low heat until it begins to thicken.
Add the butter and flour to the mixture.
Stir in the boiled asparagus, chopped fine.
Assemble and serve
Fill the rolls with the asparagus mixture, replace the tops, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main vegetable flavour and the bulk of the filling.
- Eggs
- Thicken the milk mixture as they set with gentle heat, giving the filling body.
- Milk
- Forms the liquid base of the custard, softening it into a creamy texture.
- Biscuits or small light rolls
- Act as hollow edible cases that hold the filling and soak up some of its moisture.
- Butter
- Adds richness and smoothness to the custard, with flour helping it thicken evenly.
The step that matters
Stir over low heat until it begins to thicken. Eggs set into a custard at gentle heat; high heat can curdle them into lumps, so the mixture should be stirred constantly and removed once it just thickens.
