Hot dogs were a huge staple of my youth and often the unit of measurement to describe how hungry I was ("Yeah guys I'm down to chill, I just need like three hotdogs first"). I usually opted for the standard ketchup and mustard, but when it comes to accessorizing this traditional American classic, it's a worldwide free for all.
The team at Food Republic recently created this Ultimate Hot Dog Style Guide. With 40 entries, it features everything from the fully-loaded Chicago Dog to the Japanese Octo-Dog. I highly recommend checking out the list and trying out some new varieties.
