The key to nailing this dressing is balancing the flavors of mayonnaise, Parmesan, garlic, lemon juice, and dijon mustard, which come together in a delightful harmony.Make sure you use fresh lemon juice for the best zing; it makes all the difference and really brightens up the dressing!One trick I find indispensable is to gradually whisk in the olive oil to achieve the perfect emulsion.
