Wax Beans, Pickled

Ingredients

Directions

Prepare the beans

  1. String the beans carefully with a knife.

  2. Wash the beans in cold water.

  3. Boil the beans in a kettle of boiling water for 30 minutes.

  4. Spread the beans on a cloth-covered table to cool.

Pack the jar

  1. Layer the beans and bay leaves in a 1-gallon glass jar until it's nearly full.

  2. Add ground pepper, ground black mustard, and coarse sea salt to the jar.

  3. Fill the jar with cold cider vinegar, leaving half an inch from the neck.

  4. Add whole black pepper.

Seal the jar

  1. Seal the jar with a ground glass stopper.

  2. Pour melted beeswax around the stopper, ensuring the vinegar does not touch it.

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

What each ingredient does

Young round beans
Form the main body of the pickle and take on the flavor of the brine.
Cold cider vinegar
Provides the acidity that preserves the beans and gives the pickle its sharp taste.
Coarse sea salt
Draws moisture out of the beans and seasons the brine.
Ground black mustard
Adds pungent heat and sharpness that complements the vinegar.

The step that matters

Pour melted beeswax around the stopper. The wax must seal the jar without touching the vinegar inside. Keeping the seal dry and airtight prevents leaks and spoilage, while the vinegar must stay in contact only with the beans and spices.

Swap the beans

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

  1. Black-eyed peafits about as well
  2. Beansthe original
  3. Sesamefits about as well
  4. Chickpeafits less well

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