Ever wondered what's the meaning of the word hash? Any dish which has 'hash' in its name will include chopped or diced food, usually potatoes, onions, and some kind of meat. The word is derived from the French 'hacher', which translates to ''to chop'. This time we're chopping some smoked salmon. You can use bought prepared horseradish and that will be perfectly fine. But for your convenience, we're including a recipe for that as well.
