My friend Casey wrote a post at Good. Food. Stories. about marinating and crosshatching hot dogs before grilling them. I had to try it. I marinated mine in ketchup, mustard, and tamari overnight. I cut diagonal cuts in the dogs before marinating. Teen Martha is a hot dog aficionado and she liked them a lot. I didn’t feel like it added a whole lot of flavor to mine, but it was definitely fun to give it a try.
