2 T minced fresh parsley leaves
1/4 tsp ground black pepper
2 large hard-cooked eggs, peeled and cut into 1/4 inch cubes (optional)
1. Place potatoes in large saucepan and add water to cover by 1 inch. Bring to boil over medium-high heat; add 1 Tbls salt, reduce heat to medium, and simmer, stirring once or twice, until potatoes are tender, about 8 minutes.
2. Drain potatoes and transfer to large bowl. Add vinegar and, using rubber spatula, toss gently to combine. Let stand until potatoes are just warm, about 20 minutes.
3. Meanwhile, in small bowl, stir together celery, onion, pickle relish, mayonnaise, powdered mustard, celery seed, parsley, pepper, and 1/2 tsp salt. Using rubber spatula, gently fold dressing and eggs, if using, into potatoes. Cover with plastic wrap and refrigerate until chilled, about 1 hour. Serve.
