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.
