I know I don’t have to tell you this one simple truth, that not all macaroni salads are created equal. Just go to any potluck and sample a dozen different macaroni salads, each a “secret family recipe passed down from Aunt or Granny so-and-so”, and you’ll know exactly what I mean.
Macaroni salads tend to be the victims of four cardinal sins: 1) Not enough mayo and too darn dry (you can’t be chintzy and expect good results), 2) Not enough flavor (it may be called “macaroni” salad, but that doesn’t mean it’s only about the macaroni)

Ingredients

• 2 cups dry elbow macaroni, cooked, rinsed, and drained
• 1/3 cup diced celery
• 1/4 cup minced red onion, soaked in cold water for 5 minutes, drained
• 1 tablespoon minced flat-leaf parsley
• 1/2 cup diced vine-ripened tomato (optional)
• 1/2 cup prepared mayonnaise
• 3/4 teaspoon dry mustard
• 1 1/2 teaspoons sugar
• 1 1/2 tablespoons cider vinegar
• 3 tablespoons sour cream
• 1/2 teaspoon kosher salt, plus more to taste
• Freshly ground black pepper

Directions
In a large bowl combine the macaroni, celery, onion, parsley and tomato, if using. In a small bowl, whisk together the mayonnaise, mustard, sugar, vinegar, sour cream and salt. Pour the dressing over the salad and stir to combine. Season with salt and pepper to taste. Serve. Store covered in the refrigerator, for up to 3 days.
