We tried the school bread on our 2016 trip. It had a bitter taste to the bread, and like you said, it was pretty dry. We got it fresh, either morning or early afternoon and ate it right there, so it wasn't sitting overnight or anything, but it was like eating a stale, bitter dinner roll. Not good at all. But we ate at Akershus and our server told us that real school bread is pretty different from the Epcot variety. She said it's so much better in Norway. So I'd get it again actually IN Norway if I ever go there, but I won't get the Epcot version. It makes sense...there are products that you can't get in different countries. For the longest time, I couldn't get baking soda here. They started carrying it a few years ago, but when I first moved here, I had to get it and bring it back from the states. Baking can change dramatically without the proper ingredients you are used to. One of my friends lived in...I want to say Japan? for a while and said she couldn't get peanut butter. There was something that looked like peanut butter, but it had pigs all over the label, so she figured it wasn't actually peanutbutter. I thought perhaps satay sauce. That's got a peanut butter base, but has other things in it liks soy sauce and chili paste, and garlic. You wouldn't want to put that on a PB&J sandwich. But it makes a difference to get the actual ingredients instead of trying to substitute with the next best thing.
Those salted caramel squares covered in chocolate in the Germany pavilion.....oh my goodness are those delicious. That's what I'd go for. If I had to take something from the Norway pavilion, I'd take a troll horn, probably.
