Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small onions
- Form the main body of the pickle, becoming tender and mild as they soak and absorb the vinegar.
- Salt
- Draws moisture out of the onions during the soak, firming them and reducing harsh sharpness.
- Good vinegar
- Provides the acidity that preserves the onions and gives the pickle its tangy flavour.
- Cloves
- Adds warm, aromatic spice flavour to the pickling liquid.
- Mace
- Adds a delicate, warm aroma to the pickling liquid.
- Black pepper
- Adds mild heat and a background spice note to the pickle.
The step that matters
Drying the onions before pouring the pickle. Excess surface water dilutes the hot vinegar and weakens the pickle, so the onions should be dried well before they are covered with the boiled liquid.
Swap the mace
How well each one fits the dish's main ingredients (onion, vinegar, clove, pepper):
- Allspicefits better
- Garlicfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against onion, vinegar, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
