Why it works: Nutmeg and lemon match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 11,318 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Asparagus on Toast
Ingredients
Directions
Prepare
Wash the fresh asparagus carefully and boil until tender.
Make the sauce
In a pan, cook the chopped onion, bay leaf, and peppercorns in butter until bubbling, without browning.
Gradually add flour, stirring until smooth and thick.
Add broth or milk and nutmeg, cooking for five minutes.
Strain the mixture into a saucepan.
Slowly add the beaten egg yolks and lemon juice, stirring to prevent boiling.
Add butter bit by bit, stirring until very hot without boiling.
Serve
Place the hot asparagus on pieces of hot toast and serve the sauce on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce as they set gently with heat, adding richness and a smooth body.
- Flour
- Thickens the butter and liquid into a smooth base for the sauce.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Broth or milk
- Forms the liquid body of the sauce and carries its flavor.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Adding the egg yolks. Egg yolks thicken by gentle heat, but if the sauce boils they can curdle and turn grainy. Stirring constantly and keeping the heat low keeps the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, butter, flour, chicken, nutmeg, egg, lemon):
- Leekfits better
- Shallotfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against asparagus, butter, flour, chicken, nutmeg, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
