Well, maybe not that many. I don’t know. There’s obviously near infinite variation on themes, but a cheese sandwich, a cheese sandwich with pickles, and a cheese sandwich with a gentleman’s relish really are all cheese sandwiches.
There’s an entire Wikipedia section on sandwiches … many different kinds from various countries and cultures. I think I shall start making some. Perhaps a new sandwich every week for a year. No, that’s a bit too much sandwich commitment for my liking; but I will endeavour to try a few, at least, in the coming months.
Please don’t anybody ever refer to it as a “sandwich challenge,” and if you decide for some personal reason to, in fact, make it into some sort of “challenge” please don’t feel it necessary to post photos to (anti)social media of all 100 (or however many) sandwiches that you make, or claim that you are doing it for charity or to “raise awareness.”
The Bierock sounds particularly good. It would likely keep well for days, and be suitable to be served cold in a work lunch box (don’t see many of those any more). This sandwich isn’t particularly sandwich-like in the minds of most people: It is just that fact, however, that also makes it seemingly a good candidate for freezing extras for use a few weeks or months down the road. I guess the Bierock is more like what I know as a meat pie; Wikipedia describes it as a yeast dough pastry pocket sandwich. While it looks very good it might be one of those cases where hours of time — shopping, preparation, baking — results in a product that, while good or even very good, ultimately doesn’t seem worth the time and effort to do it again.
I imagine traditionally such sandwiches were relatively more easily prepared — certainly less of an event — likely more quickly assembled with leftovers, perhaps arranged in a Dutch oven and placed directly in the hearth; not requiring a special shopping list (I don’t know when I last bought cabbage), trip to the store, planned preparation and getting organized, actual preparation, pre-heating an oven (probably just for this), baking, cooling a bit, and have a few people scarf them down, say “yeah they were good,” and leave me thinking that I could have gotten just as good (or better) reaction to a cheese and tomato sandwich.
