Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main body of the dish and gives its flavour and character.
- Milk
- Forms the liquid base of the sauce, adding body and mild sweetness.
- Butter
- Adds richness and fat, and with the flour forms the base that thickens the sauce.
- Flour
- Thickens the butter and milk mixture into a smooth, creamy sauce.
- Egg yolks
- Enrich and thicken the sauce as they set gently with heat.
- Cream
- Adds fat and smoothness, giving the sauce a richer texture.
The step that matters
Cook the sauce without boiling. Egg yolks thicken by gentle heat but curdle if boiled, so the sauce should be kept just below a boil once they are added.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, milk, lettuce, butter, flour, cream, egg):
- Leekfits better
