01 - Place the softened cream cheese, shredded cheddar, and sour cream in a medium mixing bowl. Beat with a hand mixer or stir vigorously until completely smooth and no lumps remain.
02 - Pour in the Dijon mustard, mayonnaise, Worcestershire sauce, garlic powder, smoked paprika, black pepper, and cayenne pepper if using. Mix until all seasonings are evenly distributed throughout the cheese mixture.
03 - Taste the dip and add more salt, pepper, or cayenne as desired. Remember the cheddar already provides saltiness, so adjust accordingly.
04 - Spoon the dip into a decorative serving bowl. Sprinkle the chopped chives evenly over the top for color and mild onion flavor.
05 - Serve immediately alongside warm soft pretzels. If preparing ahead, cover tightly and refrigerate. Allow refrigerated dip to sit at room temperature for 10 minutes before serving to regain ideal spreading consistency.
