I live in the us now since over 4 years and whenever I get home the first thing I desperately need and want to eat are:

• smoked salmon on white bread
• a soft boiled egg
• senfgurken (cucumbers pickled in mustard and vinegar)
• good Italian food (bruschetta,carpaccio basically antipasti in general)
  
• good vodka...
  
• thueringer bratwurst
• met broetchen (ground raw park with onions and spices on white bread)

I'm done with the first 3 things, the 4th comes tonight and the rest comes in the next couple of days.
