JohnnyBravo: it's not embarrassing. Most of our culture came from someplace else. Lot's of times Europe and Asia. So stuff that makes a yank feel comfortable is probably already there and in better quality. Think Cup-o-Noodles is better here in the US than what you can get anywhere in Asia? Or US Ice cream beats Itialian? For that matter Pizza? And lets say you got some frozen sliders from White Castle sent to you over there - do you think you could do better in Hamburg? Or anything in France. One thing I had recently in Steamboat Springs was New Mexican fry bread. You can't get that in Germany or Minnesota or probably Texas. That was American! Green Bay pan fried perch? Walleye?
If you can figure out to smuggle/import things like that to Germany you'll be a millionaire from the ex-pats and servicemen over there. The BBQ sauce is a given and the Hershey's syrup is too.
Don't be embarrassed by what we Americans think is good. Your palate is trained. Americans are trained. Everyone is trained. Think about what you miss from the states and what you'd put on those shelves. You might just get rich doing it....

pindakaas?
Wish I'd known. I bought a kilo of young gouda, a kilo of butter and some bread and it saved my life for 2 months in Skandinavia over winter where a sandwich was more than a night's stay in a youth hostel.

When I climb mountains here in Colorado, I find simple foods are appetizing: PB&J. Sometimes Mufaletta. But at 14,000 feet (4,267 meters) simple things from youth taste the best.

I did a search on their wedsite:
Peanuts not found. Peanut Butter not found.

That's American.

The Europeans already beat us chocolates, cakes, hotdogs (although they look at you sideways if you stick the sausage into the bread.) Pretty much everything.

But a decent PB&J? Pringles on the side?
