Step 1: In a medium bowl, add the cup of mayonnaise as your base. This creates the creamy foundation for your tartar sauce.

Step 2: Add the finely chopped dill pickles, minced onion, and capers to the mayonnaise. The finer you chop these ingredients, the smoother your sauce will be.

Step 3: Squeeze in the fresh lemon juice and add the Dijon mustard and Worcestershire sauce. These ingredients provide the tangy depth that makes homemade tartar sauce special.

Step 4: Sprinkle in the chopped fresh dill and garlic powder, then gently fold all ingredients together until well combined but not overmixed.

Step 5: Season with salt and freshly ground black pepper to taste, then cover and refrigerate for at least 30 minutes before serving to allow flavors to meld together.

For the best results, use a rubber spatula to gently fold in the ingredients rather than aggressively stirring. This preserves the texture of the individual components.
