This was delicious. I will be making this again. I only made minor changes. I used Yukon Gold potatoes instead of the red, I didn't have a red onion so I used a Vidalia, and I added 5 eggs instead of three. I didn't make one change to the dressing. My DH even liked it and he usually only likes his potato salad one way.
Excellent potatoe salad. I skipped the eggs as I didn't have any already boiled but we didn't miss them Instead of buttermilk I used non-fat Greek Yogurt and also used a Vidalia onion in place of the red. I also used celery seed in place of the diced celery - again because it was faster. Thanks for posting.
