You loved the prosciutto in Milan. You want to bring some home with you.
Be sure to check with US Customs to see if that is permitted to come home with you. You might just have to eat it there.
You may have to pay an extra fee, the food may be confiscated, or in some cases you may have a penalty attached. And don't think you can hide it in your suitcase. Those dogs in customs can smell more than just drugs...they smell food as well.
