We put this dressing in a squeeze bottle and drizzle it on virtually everything that comes off the restaurant’s spit or grill: dry-aged rib-eye steak, lamb chops, chicken, whole fish, shellfish, even grilled vegetables. The capers, garlic, oregano, and lemon impart an instantly recognizable Greek taste. To keep the dressing fresh and vibrant, we combine all the ingredients except for the lemon juice in the morning. Then, in small batches as needed throughout the day, we whisk in the lemon juice. You can do the same at home if you need to prepare the dressing ahead.
