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

What each ingredient does

Granulated sugar
Provides sweetness and balances the sharpness of the vinegar.
White vinegar
Provides the acidity that pickles the onions and gives them their tang.
Green onions
Form the main body of the pickle and take on flavor from the syrup as they soak.
Mustard seed
Adds a sharp, aromatic flavor that carries through the pickling liquid.
Celery seed
Adds a savory, herbal aroma that complements the onions.

The step that matters

Cool the syrup before adding the onions. The recipe says to cool the syrup, then add food coloring; the record does not say to pour the syrup over the onions while hot, so the cook should follow the stated order of cooling first. Hot liquid would soften the onions and cause the food coloring to be unevenly distributed.

Flavor stand-ins for the celery

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

  1. Capersbetter flavor fit
  2. Garlicbetter flavor fit
  3. Tarragonbetter flavor fit
  4. Celerythe original

Fit is the average pairing score against sugar, vinegar, onion, mustard. 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).
