Asparagus a LA Francaise

Ingredients

Directions

Prepare the asparagus

  1. Trim the asparagus.

  2. Place the trimmed asparagus in boiling water with salt and carbonate of soda.

  4. Drain the asparagus and dry on a clean cloth.

Make the sauce and serve

  1. Melt the butter in a clean stewpan.

  2. Add the asparagus to the pan.

  3. Stew the asparagus over medium heat for 8 to 10 minutes, shaking often.

  4. Sprinkle the flour and sugar over the asparagus.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Asparagus
Is the main vegetable, cooked until tender and then finished in the buttery sauce.
Egg yolks
Thicken the sauce as they set with gentle heat, giving it body and a smooth, rich texture.
Butter
Provides fat for richness and carries flavour through the stewed asparagus.
Flour
Thickens the cooking liquid so the sauce clings to the asparagus.

The step that matters

Stirring in the beaten egg yolks. Egg yolks thicken when heated but can scramble if the sauce is too hot or boiling. Remove the pan from direct heat or keep it gently warm while stirring so the sauce stays smooth and glossy.

Swap the asparagus

How well each one fits the dish's main ingredients (butter, flour, sugar, egg):

  1. Chivefits about as well
  2. Leekfits about as well
  3. Shallotfits about as well
  4. Asparagusthe original

Fit is the average pairing score against butter, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
