  2. Optionally, add finely mashed hard boiled eggs.

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

What each ingredient does

Oyster liquor
Provides the main briny, savoury flavour of the sauce.
Buttermilk
Adds tang and a creamy body to the sauce.
Flour
Thickens the liquid so the sauce coats the spoon.
Lemon peel
Adds bright aromatic oils that lift the flavour.
Hard boiled eggs
Adds richness and body when mashed into the sauce.

The step that matters

Adding the flour. Flour must be stirred in so it disperses without lumps; it thickens as starch granules swell in hot liquid, so adding too much makes the sauce pasty rather than thin.

Swap the mace

How well each one fits the dish's main ingredients (oyster, lemon, buttermilk, pepper, flour, egg):

  1. Parsleyfits better
  2. Dillfits better
  3. Tarragonfits better
  4. Macethe original

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