Asparagus, Pompadoue

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, combine the butter, salt, mace, red pepper, egg yolks, lemon juice, and cold water.

  2. Place the saucepan in boiling water and stir continuously with a whisk until the sauce thickens.

Assemble and serve

  1. Remove from heat and layer the asparagus on a dish, followed by two layers of sauce.

  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
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):

  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.
