This recipe utilizes the high protein density of Greek yogurt to engineer a structurally sound, velvety tartar sauce that achieves classic flavor complexity through precise ratios of acid, salt, and a mandatory two-hour rest period.
The two-hour minimum rest period in the refrigerator is non-negotiable for achieving complex, unified flavor through flavor diffusion. If the sauce is too thin after mixing, strain the Greek yogurt through a coffee filter for thirty minutes prior to beginning. This recipe makes approximately 1 1/4 cups and should be stored in an airtight container, consumed within three days for peak freshness. If a small amount of clear whey separates during chilling, gently fold it back into the sauce once.
