Let's be frank: Hot dogs aren't exactly posh. They may be popular with children and with baseball fans at ball parks, but you're not likely to find wieners sharing table space with escargot. There's no real way to transform a plate of hot dogs into an elegant dish, so don't try. Instead, just spruce them up a little, and focus on making them so mouthwateringly delicious that even hardcore foodies will be begging for a bite.
As a general rule, the cheaper the dog, the lower the quality, so be sure to pick up some of the pricier franks at your local supermarket. All-beef dogs from brands such as Hebrew National or Vienna are always a safe bet. To bring out the frankfurter's flavor, grill it.
To differentiate your upscale dogs from typical pedestrian franks, use petite baguettes instead of hot dog buns. If you really want to shake things up, try enveloping a dog and all its toppings in a corn or flour tortilla. Shredded cheese and sauerkraut both make excellent, top-shelf toppings on any quality hot dog, but if you just want to relish the taste of the frank itself, try adding a bit of salt-free ketchup. Not only is it better for you, it also has a richer, more tomatoey taste than regular ketchup.
