Skordalia is a thick purée in Greek cuisine, made of garlic in a base of potatoes, walnuts, almonds or liquid-soaked stale bread mixed with olive oil in to make a smooth emulsion, to which some vinegar is added. It is usually made in a mortar and pestle. Skordalia is served as a garnish or side dish. It is mainly served with batter-fried cod, especially during Lent and on the Greek national holiday of March 25th. In the Anglosphere, it is promoted as a dip.
