I like buying the Kosher hot dog brands because quite frankly (no pun intended), most hot dog brands contain nothing but crappy, unhealthy over salted fillers with all pieces and parts of God only knows what in them.
My mom used to use a knife to cut a cross in the ends of the hot dog. When they cook, the very ends of the hot dogs splay out and they not only look good, they seem to taste better when the ends are exposed to the grilling or skillet cooking. If you cut deeply to make the cross, the ends of the hot dog will curl and look so festive and brown nicely.
I love grilled hot dogs, but also like them cooked in a cast iron skillet. Boiling is my least favorite way to eat a hot dog. Because a hot dog is already cooked when processed, much like Bologna, hot dogs are easy to heat and serve. You can place them directly on the grill or put them in a skillet with just a tad of oil spray. There is already fat in hot dogs, so not much is needed to heat them.
We would sautee onions and mix in some ketchup to put it on hot dogs. My mom used to also mix chopped pickles with mustard for our hot dogs as well. But, a dollop of chili and some shredded cheese is an all time favorite. Even still there is nothing like a hot dog with plain yellow mustard. We only use the split top hot dog buns because the side cut ones always fall apart.
My dad used to line his hot dog bun with potato chips because he liked some crunch in every bite!
Gosh, a flood of memories of my parents came back of the days gone by when we used to have grilled hot dogs in the back yard using a hibachi grill. Those were the days, my friend!!
