The street vendors in NYC boil their dogs and store them in hot water in the cart. I prefer mine grilled, but I find airfried acceptable. As a last resort, I will nuke them for exactly 1 minute and 10 seconds, put them in the bun and add the condiments, then 10 more seconds in the microwave to soften up the bun. My condiments of choice are mustard (horsheradish, spicy brown, or screaming yellow), and either sweet pickle relish or Ted's Hot Dog Sauce. No kraut and, for Buddah's sake, no ketchup! Save the ketchup for the fries. When I travelled for work, if I was going through Chicago I would just HAVE to hunt down the Chicago hot dog vendor.
