Oddly enough, I think the recipe was incomplete. It called for garlic powder and onion powder, neither of which was in the directions. So I included it in the buttermilk dressing portion. Also the directions didn't say anything past halving the potatoes but I ended up mashing them slightly to give it more of a traditional potato salad texture.
No drink tonight - I did have a beer but it was gone before I could photograph it.
Oh, and for those of you more interested in the whoopie pies:
I made too many potatoes I think. There wasn't enough dressing to hold everything together. And I think it would've been more flavorful with more dressing. But we both made something yummy while constantly stepping over each other, which is an accomplishment in and of itself. =o9
