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

Flavor stand-ins for the parsley

The recipe marks parsley as optional. How well each one fits the dish's main ingredients (milk, butter, flour, white pepper):

  1. Nutmegbetter flavor fit
  2. Cinnamonbetter flavor fit
  3. Maceabout as good a flavor fit
  4. Parsleythe original

Fit is the average pairing score against milk, butter, flour, white pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
