To Pickle Green Peppers
Ingredients
Directions
Prepare
Gather young bell peppers and slit one side to remove the core without damaging the shell.
Brine and pickle
Place the peppers in boiling salted water, changing the water daily for three weeks.
Keep the peppers covered in a warm place and stir them several times a day.
When they turn a fine green, transfer them to a jar.
Pour cold vinegar over the peppers and add a small piece of alum.

What each ingredient does
- Bell peppers
- Provide the main body and shell that soften and turn green during the pickling.
- Coarse sea salt
- Draws moisture out of the peppers and helps preserve them during the long soak.
- Cold vinegar
- Adds acidity that preserves the peppers and gives the finished pickle its sharp flavour.
- A small piece of alum
- Helps the peppers keep a firm, crisp texture in the finished pickle.
The step that matters
Slit the peppers without damaging the shell. A torn or broken shell lets air and spoilage microbes reach the flesh during the long soak, which can cause rot and soft spots. Keeping the shell intact protects the pepper throughout the pickling.
