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

What each ingredient does

String beans
The main vegetable that is softened by brining and then flavoured by the vinegar.
Coarse sea salt
Draws water out of the beans during the long brine and seasons them.
Vinegar
Provides acidity that preserves the beans and gives the pickle its sharp flavour.
Alum
Helps the beans stay firm and crisp during scalding.

The step that matters

Rinsing after the brine. The beans must be rinsed well after the 24-hour brine so excess salt is removed; otherwise the pickle will taste overly salty. Draining afterward also keeps extra water from diluting the vinegar.

Swap the beans

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

  1. Chickpeafits better
  2. Pistachiofits about as well
  3. Sesamefits about as well
  4. Beansthe original

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