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

What each ingredient does

Fresh beans
The main vegetable, which takes on the brine's salt and the vinegar's sharp flavour as it pickles.
Coarse sea salt
Draws water out of the beans and seasons them through the brine.
Boiling hot vinegar
Its acidity preserves the beans and gives the pickle its sharp, tangy taste.
Black pepper
Adds a warm, sharp aroma and spice to the pickled beans.
Mace
Adds a warm, delicate aroma that flavours the vinegar and beans.
Cloves
Adds a strong, sweet-spicy aroma that deepens the pickle's flavour.

The step that matters

Pouring boiling vinegar over the beans repeatedly. Hot vinegar penetrates the beans and brings their acidity into the vegetable, which is what preserves them. Pouring it again over several days keeps the acid working until the beans are fully pickled.

Swap the mace

How well each one fits the dish's main ingredients (beans, vinegar, pepper, clove):

  1. Allspicefits better
  2. Cinnamonfits better
  3. Cuminfits better
  4. Macethe original

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