When I came back to Norway, I took an "Interrail" trip with some friends. This meant bringing our own food. My favorite on sandwiches was the all-American peanut butter and jelly. My Norwegian friends thought it was gross. Well, my dear Norwegian friends, here's more edible grossness from "over there": Reindeer poop.
An alternative in Norway is to take a candy like Toffin (one of my favorites) and deliver the Reindeer poop poem (see link) with it. (Snowman poop includes marshmallows.)
I kid you not. :-)
