Not toasting the buns
Typically, hot dogs are a rather simple food. You should show attention to each component, especially the bun, to get the most out of each dog. It may seem as though toasted buns are a luxury that will make you excluded from any BBQ where your brother-in-law will be present. They are nevertheless indisputability superior to untoasted buns, and you must lust over them.
The problem is that grilling shouldn't be used to toast buns. They can toast very unevenly and will absorb any unpleasant grill debris. Hot dog buns can be toasted in a skillet after being brushed with a little oil or butter to seal the split interior. A good approach to produce these babies in large quantities is to put a sheet pan of split and oiled buns under the broiler while throwing a party. No matter how you toast, be sure to watch those buns to avoid scorching.
