Mustard! Isn’t it wonderful, friends? This is a roast pork sandwich, consisting of roast pork and Swiss cheese. That’s not quite enough, unless you’re dealing with the absolute best in pork, and what are the odds that any given establishment you happen to find yourself in is offering the best possible roast pork? Not very good, by my estimation. But mustard! A healthy application of mustard brings a savory spiciness that brings a drab sandwich all the way up to perfectly acceptable. Let me be clear: I am not praising the sandwich, which absent the influence of mustard I found to be rather unimpressive. Rather, I wish to hail the transformative power of mustard. And this was yellow mustard, the absolute least of all mustards! So many different types, each wonderful in their own way, and each capable of doing so much for a sandwich. In the quest for the rarefied air of the sandwich world, it’s easy to lose sight of the everyday pleasures, the sorts of things that are constantly at work in making the average sandwich so darned enjoyable. Take a minute sometime to appreciate mustard. It’s given you so much, a small thank you isn’t much to ask.
