Begin by gathering all your ingredients.
Having everything at your fingertips will simplify the preparation process.
Combine the mayonnaise, diced dill pickles, and chopped capers in a medium bowl.
Make sure these are mixed well to ensure a uniform distribution of flavor.
Add in the lemon juice, Dijon mustard, and minced garlic.
These ingredients will add the essential tangy and zesty elements to your sauce.
Sprinkle in the onion powder and sea salt.
Stir everything together until you achieve a smooth and well-mixed consistency.
Let the sauce rest in the refrigerator for at least 1 hour before serving.
This allows the flavors to meld beautifully.
