You might be surprised to find out you've been cooking and eating hot dogs all wrong! The best way to cook one is to cut it into a spiral shape and then throw it on the grill. You can easily do this by putting the hot dog on a skewer, cutting it with a knife at a slight angle, and then rotating the dog while cutting on the same angle.
Once it's cooked, you'll have a longer hot dog that fills up the bun and it cooked more evenly. It also holds condiments much better!
