In my experience,sometimes you can get the food items one looks for in Switzerland,but they are often called differently, but are basically or very similar to the ones one knows from home.Well this goes for basic ingredients of course,not necessarily the branded stuff.

I took the time a long time ago to write up a lexicon in five lingos about all things food related, it's not complete and even not in alphabetical order,but it has been helpful to many an expatriate so far

And I think Jack of www.laughinglemon.ch has something similar on his website.

anyhoo, to add to the list of Andrea

and not foodie related but also something expats from America often miss, here's a swiss based online shop for scrapbooking
