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

What each ingredient does

Drawn butter
Provides fat that carries flavour and gives the sauce a rich, smooth body.
Fresh egg yolks
Thicken the sauce as they warm and help bind the butter and milk together.
Sweet milk
Adds moisture and dilutes the yolks so they blend smoothly into the butter.
Hard boiled eggs
Add texture and body through their chopped whites and yolks.

The step that matters

Stirring the yolk mixture into the hot butter. Egg proteins thicken as they warm, but too much heat scrambles them into lumps. Keep the heat gentle and stir constantly while the sauce thickens.

Swap the parsley

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

  1. Nutmegfits better
  2. Cinnamonfits better
  3. Parsleythe original
  4. Tarragonfits less well

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