Macaroni Salad

Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until tender (about 1 minute past al dente). Drain and let cool to room temperature.

Meanwhile, in a large bowl, whisk together the mayonnaise, sour cream, sugar, mustard, vinegar, water, salt, pepper, and onion powder.

Add the cooked pasta, carrots, celery, bell pepper, scallions, and basil to the bowl and stir until evenly combined. Taste and adjust seasoning if necessary. Serve the salad immediately or let it sit for up to an hour at room temperature before serving. (Keep in mind that the dressing will thicken and get absorbed by the noodles as the salad sits.)
