If you haven't done a roasted potato salad then go make one right now. Use the same sauce but just cube and season and roast the potatoes. I actually roast mine with coarsely chopped onions too. It's a whole new potato salad world. I can remember the last time I boiled. The texture is awesome.
Smokejumper uses red potatoes that we smoke-roast on the BGE, then we use something like a mustard vinaigrette and bacon to complete his potato salad. It is somewhat like German Potato Salad. And very good, although, at that point, some potatoes are lost to testing usually.
I prefer to steam the potatoes, I use red or Yukon Golds, either way, steamed in skins, then rubbed clean. The steaming introduces less water and seems to cook more evenly.
