Step 1: Cook the Macaroni: Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package directions until al dente. Drain the macaroni and rinse with cold water to stop the cooking process. Ensure the macaroni is thoroughly drained before proceeding.
Step 2: Prepare the Dressing: In a large bowl, whisk together the mayonnaise, sweet pickle relish, yellow mustard, white vinegar, granulated sugar, salt, and black pepper until well combined. Taste and adjust seasonings as needed. The dressing should be creamy, tangy, and slightly sweet.
Step 3: Combine Ingredients: Add the cooked and drained macaroni, diced celery, red bell pepper, and minced red onion to the bowl with the dressing. Gently fold all the ingredients together until the macaroni and vegetables are evenly coated with the dressing. If using, add the chopped hard-boiled eggs and fold gently to incorporate.
Step 4: Chill and Serve: Cover the bowl with plastic wrap and refrigerate for at least 2 hours to allow the flavors to meld. Chilling the salad is essential for optimal flavor and texture. Before serving, give the salad a gentle stir. Serve cold and enjoy.
Optional Tips: For a tangier salad, add an extra tablespoon of white vinegar or a squeeze of lemon juice. For a sweeter salad, increase the amount of sugar to taste. Diced ham or shredded cheddar cheese can be added for extra flavor and protein. If the salad seems dry after chilling, add a little more mayonnaise to reach the desired consistency. Experiment with different types of pickles or relishes to customize the flavor.
