Asparagus a LA Francaise

Ingredients

Directions

Prepare the asparagus

  1. Boil a large pot of water with salt and a few grains of baking soda.

  2. Add the asparagus and cook for 10 to 12 minutes until tender.

  3. Drain the asparagus and spread it on a clean cloth to dry.

Make the sauce

  1. Melt the butter in a clean saucepan over medium heat.

  2. Add the asparagus and sauté for 8 to 10 minutes, shaking the pan often.

  3. Sprinkle in the flour and sugar, then pour in boiling water to nearly cover the asparagus.

  4. Boil rapidly until little liquid remains.

  5. Stir in the beaten yolks of the eggs.

Serve

  1. Serve the asparagus hot, heaped on a dish with the sauce adhering.

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 butter sauce.
Butter
Provides fat and richness, carrying flavour into the sauce and coating the asparagus.
Flour
Thickens the cooking liquid so the sauce clings to the asparagus.
Eggs
Their beaten yolks enrich and thicken the sauce as it sets.

The step that matters

Stir in the beaten yolks of the eggs. Egg yolks thicken when heated gently; if the sauce is too hot or boiled after adding them, they can scramble and turn grainy instead of smooth and creamy.

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

  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.
