Pickling your own olives is a very easy task. The hardest bit is waiting patiently for 1 month while they pickle away, but rest assured the results are well worth it. Put your own stamp on this recipe by adding whatever herbs and spices you prefer. You will need 4 good-sized glass jars, washed and sterilised with boiling water and one uncooked whole egg in its shell for testing salt levels in the water.
