Pasta Preparation: Begin by boiling a large pot of water seasoned with salt. Add the pasta and cook it until al dente, as per the instructions on the packaging. Once cooked, drain the pasta using a colander and rinse briefly under cold water to halt the cooking process and prevent the noodles from sticking together. Ensure thorough drainage before transferring the pasta to a large mixing bowl.
Dressing Preparation: In a separate, smaller bowl, combine the mayonnaise, sour cream, dill pickle juice, onion powder, and chopped fresh dill. Stir these ingredients together until the mixture is smooth and uniform.
Assembling the Salad: Add the prepared dressing to the bowl containing the cooled pasta. Follow this by adding the diced dill pickles and cubes of sharp cheddar cheese. Mix these ingredients gently yet thoroughly to ensure that the pasta is evenly coated with the dressing and the pickles and cheese are well-distributed throughout the salad.
Seasoning and Garnishing: Season the salad with kosher salt and freshly ground black pepper according to your taste preferences. Finally, garnish the salad with additional chopped fresh dill. This not only enhances the flavor but also improves the visual appeal of the dish.
