The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Asparagus
- Forms the bulk of the dish and provides its main vegetable flavour and tender texture.
- Butter
- Adds fat and richness, and helps coat the asparagus as it warms.
- Flour
- Thickens the liquid into a smooth sauce as it simmers.
- Egg yolks
- Enrich and thicken the sauce, giving it a creamy body when gently heated.
- Milk
- Adds moisture and creaminess, mellowing the sauce with dairy richness.
The step that matters
Simmer gently after adding the egg yolk and milk mixture. Egg yolks thicken by gentle heat but can curdle or turn grainy if the sauce boils hard, so keep the heat low and the sauce moving only slightly.
