After 10 days, wash the olives under running water and perform a final rinse with cold vinegar.

Arrange the olives on a baking sheet greased with oil. The olives must not be piled up.

Place the olives in the oven at 150 ° C for about 10 minutes or until the surface of the olives is wrinkled.

Remove the plate and let it cool. Transfer the olives into sterile and hermetically sealed jars, filled with oil. Wait a few hours for the oil to penetrate any interstice, bring the oil to level and close.
