Wash you veggies and then cut them in sticks or rounds as appropriate.
Take a large pot and place on medium heat. Add the water and the salt along with the peppercorns, coriander and all-spice and bring to a boil. Simmer for 5’ for the salt to be diluted. Remove from the heat and allow to cool.
Add to the salted water the vinegar and mix.
Place the veggies in jars and fill with the above pickling juice. Add parchment paper on top of them and press lightly to keep them submerged. Keep in a cool place for 1 week for pickling and then refrigerate.
