Asparagus, Pompadour

Ingredients

Directions

Prepare the asparagus

  1. Prepare the asparagus by tying it in bundles and cutting off the hard parts, leaving only the tender parts.

  2. Cook the asparagus in boiling water seasoned with salt until tender, then drain and keep warm.

Make the sauce

  1. In a saucepan, melt the butter and add salt, mace, red pepper, egg yolks, lemon juice, and cold water.

  2. Place the saucepan in boiling water, stirring continuously with a whisk until the sauce thickens.

Serve

  1. Remove from heat and layer the asparagus on a dish, then pour the sauce over it twice.

  2. 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
Main vegetable; cooking softens its fibres into a tender texture.
Butter
Fat that enriches the sauce and gives it a smooth, rich body.
Egg yolks
Thicken the sauce as they heat and help bind the butter and liquid together.
Lemon juice
Adds acidity that brightens the sauce and balances its richness.

The step that matters

Thickening the sauce over boiling water. Egg yolks set when heated, so if the sauce gets too hot or is not stirred constantly it can curdle or scramble. Gentle, steady heat and constant whisking keep it smooth and thick.

Swap the mace

How well each one fits the dish's main ingredients (asparagus, butter, pepper, egg, lemon):

  1. Parsleyfits better
  2. Tarragonfits better
  3. Thymefits better
  4. 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.
