Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Asparagus, Pompadoue
Ingredients
Directions
Prepare the asparagus
Prepare the asparagus by tying it in bundles and cutting off the hard parts, leaving only the tender parts.
Cook the asparagus in boiling water seasoned with salt until tender, then drain and keep warm.
Make the sauce
In a saucepan, combine the butter, salt, mace, red pepper, egg yolks, lemon juice, and cold water.
Place the saucepan in boiling water and stir continuously with a whisk until the sauce thickens.
Assemble and serve
Remove from heat and layer the asparagus on a dish, followed by two layers of sauce.
Serve hot with a spoon; eat with a fork.

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 provides its tender, vegetal texture.
- Unsalted butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Egg yolks
- Thicken the sauce as they gently set with heat and emulsify the butter.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances the butter and yolks.
The step that matters
Thickening the sauce over boiling water. Egg yolks can scramble if they get too hot. Gentle, continuous whisking over simmering water heats them slowly so they thicken smoothly into an emulsion rather than curdling.
Swap the mace
How well each one fits the dish's main ingredients (asparagus, butter, pepper, egg, lemon):
- Parsleyfits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against asparagus, butter, pepper, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
