Place an olive on the board and hit it gently with the mallet, a hammer, or a rolling pin, so that you can easily remove the stone. Do as many as you like. Place your olives in fresh water and change that water twice a day for eight days. On the eighth day they should be slightly bitter, but not as much as a fresh olive. If they are too bitter for your taste, continue to change the water until their taste suits you.
Drain them and spread them out on a cloth to absorb excess water.
Place olives in bowl and mix all ingredients together, except for the olive oil. Place the olives in suitable jars and cover with oil. Apply lid. These olives will keep for 2 – 3 months refrigerated.
