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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the mixture into a thick, custard-like filling as they cook.
- Milk
- Forms the liquid base of the custard, giving a soft, creamy texture.
- Asparagus
- Provides the main vegetable flavour and tender texture in the filling.
- Biscuits or rolls
- Dried in the oven, they form a sturdy, absorbent shell for the filling.
- Butter
- Adds richness and a smooth, silky mouthfeel to the custard.
The step that matters
Return the strained mixture to the heat. Egg proteins set as the mixture warms, so heat must be gentle and steady. Overheating can curdle the eggs, leaving a grainy custard instead of a smooth, thickened filling.
