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

What each ingredient does

Silver onions
Provide the main body and crisp-tender texture of the pickle.
Strong brine
Salt draws out moisture and seasons the onions before pickling.
Milk
Its proteins and fats mellow the sharp sulfur bite of the onions.
Hot vinegar
Acidity preserves the onions and gives the pickle its tangy flavor.
Mace
Adds a warm, aromatic spice flavor to the vinegar.

The step that matters

Simmering in milk and water. Simmering only a short time softens the onions gently while keeping them firm. Longer cooking breaks down their cell walls, leaving them soft and mushy in the jar.

Swap the mace

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

  1. Garlicfits better
  2. Tarragonfits better
  3. Celeryfits better
  4. Macethe original

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