Ingredients

Directions

Prepare the cucumbers

  1. Quarter cucumbers, remove seeds and rinds.

  2. Cut cucumbers into 1‑inch lengths and boil in salted water for 15 to 18 minutes.

  3. Press water from cucumbers with the back of a spoon and pass through a sieve.

Make the sauce

  1. Mix cucumbers with béchamel sauce without boiling again.

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

What each ingredient does

Cucumbers
Provide the main body and mild, fresh flavor of the sauce.
Béchamel or thick white sauce
Forms the creamy base that gives the sauce its body and smooth texture.
Egg yolks
Enrich the sauce and thicken it gently when stirred in without boiling.
Chili vinegar or lemon juice
Adds acidity that brightens the flavor and balances the richness.

The step that matters

Stirring in the egg yolks. Egg yolks thicken when gently heated but can scramble and curdle if the sauce boils. Adding them just before serving, off the boil, keeps the sauce smooth.

Swap the cucumber

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

  1. Mustardfits better
  2. Capsicumfits about as well
  3. Horseradishfits about as well
  4. Cucumberthe original

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