The origins of colatura di alici date back to ancient Rome, where a similar sauce known as garum was widely used as a condiment.[3] The recipe for garum was recovered by a group of medieval monks, who would salt anchovies in wooden barrels every August, allowing the fish sauce to drip away through the cracks of the barrels over the course of the process. Eventually the process spread across the region and was perfected by using wool sheets to filter the fish sauce. One common way this fish sauce has been used is in a dish called spaghetti alla colatura di alici, which includes small amounts of the fish sauce with spaghetti, garlic, and olive oil.[1]
