When I see the term "haute dog" the hair on the back my neck stands up and all kinds of warning flags appear. Add to this the involvement of a chef and you are looking at a recipe for disaster. Pretzel dough? Maybe for a change of pace, but I prefer a quality food service individually baked hot dog bun. White truffle butter, duck foie gras, black truffles, ketchup (gasp!), vidalia onions, and black truffle dijon mustard?!! Is there a frankfurter in there? I call this a witness protection hot dog. The frank is hidden and/or buried under all that garbage.
Let me give you some advice. If you're in the area, go to Papaya King, order a hot dog (which I guarantee is better than this abomination) and save yourself $67 and change. Unless of course the woman pictured is included in the $69. She should be for that price.
I'm begging you, please leave the hot dog alone. Don't desecrate it with your crazy inventions. It's not broke, don't fix it. Stick with what you do best, high end food.
