I dunno about you, but I don't like crustless sandwiches
Those dainty, fey tea sandwiches aside, I do not understand why people would de-crust bread when making a sandwich.
It's not so much that I like the taste of the crust, it's just that I think a sandwich tastes better with the crust -- and it just looks better, more "normal" if you will.
Who else is with me?
In Japan there are packaged prepared sandwiches (on white bread) called Lunch Pack and they are all trimmed to remove the crust. Yukk.
Never an issue one way or the other. My grandmother used to like to cut the crusts off sandwiches and cut them into four triangles, which I thought was nice.
My father would not cut the crusts off, and cut the sandwich horizontally in two, and I thought that was equally nice.
I'm much more concerned with what's inside the sandwich than what surrounds it (or doesn't, as the case may be). I can't think of the last time I had a sandwich with the crusts cut off, except for tea.
It really, really depends. If you had asked me this as a kid, I'd have told you that the sandwiches HAD to be crustless, since the ones served to me at friends' houses were on the soft, Wonder-type bread. It never failed to amaze me and gross me out how the crust would like, detach in one looooong disgusting strip. I would gag every last time. OTOH, if was good bread? I was in heaven, and so it remains to this day.
Oh, unless I'm going all infantile and eating pb&j on Wonder-type bread, which I now can do with impunity and it happens about once a year. I like it when the jelly sort of seeps through, and the crust is totally necessary for texture and as a retaining wall. :)
With Wonder bread when I was a kid (or other generic flavorless white bread) - no crust is better. Especially if the bread is a little stale (which happened in our home), the crust starts to resemble stale-flavored thin cardboard. That said, we didn't get to throw out the crusts because it would be wasting food.
For good bread, like the Pepperidge Farm brand or the stuff we get now that I'm choosing, sandwiches with crust is definitely better.
I like your retaining wall analogy. That's so true. :-)
Tea sandwich no crust
Crusty bread must have crust. Sometimes if sandwich filling doesn't not reach the end I will avoid but in the whole I prefer a samdwich with crust.
