Creamy Dill Potato Salad with Eggs

I've tried numerous potato salad recipes.  I have several favorites for more of a specialty-type potato salad, but this is more of a creamy potato-and-hard-boiled-egg salad.  I found the recipe on Allrecipes but took some liberties and made several changes.  The original recipe is titled:  My Sister's Favorite Potato Salad...Ever.

Creamy Dill Potato Salad with Eggs

12 red potatoes, cut into 1" chunks

6 hard-boiled eggs, chopped

1/2 cup mayonnaise

1 cup sour cream

1/2 cup red wine vinegar

1 tablespoon mustard powder (or 2 tablespoons Dijon mustard)

2 tablespoons dried dill weed

1 teaspoon celery seed

1 teaspoon salt

freshly ground pepper, to taste

1.  Place cubed potatoes in a large pot with water to cover.  Bring to a boil and cook for 15 minutes.  Drain and allow to cool.

2.  In a large bowl, combine all ingredients.  For best flavor, refrigerate overnight.
