Pesto in the Mortar and Pestle
NOTE: To pit the olives, place them on a work surface, cover them with parchment or waxed paper and whack them firmly yet gently with a rolling pin. This splits them open, making the pit easy to remove. In general, olives are salty so the additional salt isn’t necessary. When looking for olives, if you cannot find those mentioned below, use a generic French olive.
