This is done by a procedure that consists in putting the olives into a caustic soda bath to extract the acidity. They must be preserved in brine afterwards. (highly concentrated salty solution).
They can also be eaten uncooked. To make this possible, after picking the up, before being ripe, they must be smashed and put in water that must be changed daily for ten days. Then they can be preserved in brine and seasoned according to one`s taste. There are different ways of doing it: with herbs (fennel, laurel, etc.) or adding some spices such as garlic or pepper, for instance.
To eat olives at the beginning of a meal produces a stimulation of the digestive tract, but, taking into consideration their high salty content, it is not very suitable to eat many, specially in cases of hypertension or obesity.
