What each ingredient does

Young white runner beans
Form the main body of the pickle, providing a crisp, tender bite once blanched.
Brown pickling vinegar
Adds acidity that sharpens the flavour and helps preserve the beans.
Baking soda
Raises the alkalinity of the boiling water, which helps beans keep a bright green colour.

The step that matters

Plunging the beans for 1 minute. A short blanch softens the beans just enough for pickling while keeping them crisp. Over-boiling breaks down the cell walls, leaving the beans soft and limp in the jar.
