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, Pompadour
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 whisk continuously until the sauce thickens.
Remove the saucepan from heat.
Serve
Layer the asparagus on a dish, then add two layers of sauce.
Serve hot with a spoon. Eat with a fork.

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.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 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 main body of the dish, with its tender texture carrying the sauce.
- Unsalted butter
- Adds richness and a smooth, silky body to the sauce.
- Egg yolks
- Emulsify with the butter and thicken the sauce as they gently cook.
- Lemon juice
- Adds acidity that brightens the rich butter and egg sauce.
The step that matters
Whisking the sauce over boiling water. Egg yolks scramble if they get too hot. Gentle, constant whisking over simmering water heats them slowly, so they thicken into a smooth sauce 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.
