Cucumbers a LA Poulette

Ingredients

Directions

Prepare the cucumbers

  1. Peel and slice the cucumbers evenly, then soak them in a mixture of salt and vinegar for 30 minutes.

  2. Drain the cucumbers using a cloth and place them in a saucepan with the butter.

  3. Fry the cucumbers over medium heat without browning them, then sprinkle with flour.

Make the sauce

  1. Add the broth and skim off any fat that rises to the surface.

  2. Simmer gently until the sauce reduces, ensuring the cucumbers remain intact.

  3. Stir in the egg yolks, parsley, sugar, and season with salt and pepper.

  4. Bring to a boil and serve.

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

What each ingredient does

Cucumbers
Provide the main vegetable body, which softens and absorbs the sauce as it simmers.
Butter
Fats the pan for frying and carries flavour through the cucumbers.
Flour
Thickens the broth into a smooth sauce when cooked with the butter.
Broth
Forms the liquid base of the sauce that the cucumbers cook in.
Egg yolks
Enrich and thicken the sauce, giving it a creamy texture when heated gently.

The step that matters

Adding the egg yolks. Egg yolks thicken through gentle heat, but if the sauce boils after they go in, they can scramble and turn grainy. Keep the heat low once they are stirred in.

Swap the cucumber

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

  1. Shallotfits better
  2. Capsicumfits better
  3. Chivefits about as well
  4. Cucumberthe original

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