You know what this is. When you slap a sandwich together, then decide you need a plate after all, so you put the sandwich down on the counter for a sec to grab the plate. Of course you don't realize there's a spot of water on the counter--you don't realize it until, that is, you bite into... WET BREAD. Why, God, why?!
OK, there are other ways to get wet bread. Do you like mustard? Ketchup? You know if you don't shake it just right, or enough, the first thing out of the squeeze bottle is water? Doesn't matter if you have a plate or not.
Wow. Apparently, to avoid the scourge of wet bread, one must be careful always to have a plate at all times and never squeeze condiments directly onto the bread without testing first. Either I am a hugely lazy slob (always a possibility), or y'all're just anal about sandwiches.
In Italy they have this kind of bread, looks like bagels cut in half, that is sold dried. Tough, crusty, solid; you could play hoops with it. Now you get yourself some lukewarm water and dip the bread in it quickly, then let it sit for half a minute and re-hydrate. Then eat. It sounds kind of disgusting but I came to like it. It's a traditional kind of thing, probably a way of storing bread for months after grain harvest and milling. Prolagus might come up with a name for it.
