The cucumber one is sliced cucumbers and thinly sliced onions that have been marinated in vinegar.
The British use white bread according to snugs, with butter on the bread.
Mupcat uses white bread also.
I was going to use a heavy wheat bread but mupcat convinced me to try it with white. It's really good.
I'm glad I tried it the traditional way, but I still have some cucumbers left, so wheat bread is next!

Yeah, that's really one of my favorites and when the urge strikes to have that particular sandwich, nothing else will satisfy.
I actually let the combination marinate overnight in full strength apple cider vinegar if possible. Butter is also key and needed to get a little relief from the zing of the vinegar. Oh----and salt and pepper.
