The holy oil is a typical preparation of Sicilian tradition. It's a spicy oil derived from the maceration of dried or fresh chili peppers in olive oil. In Sicily and other southern regions, holy oil is present in many recipes and is always found in household pantries. The name "holy" comes from a Sicilian saying, due to the ability of this oil to miraculously flavor every type of dish: from appetizers to side dishes, through first courses based on meat or vegetables.
