It's nice to have several "go to" recipes for quick appetizers for when you have impromptu parties. They could be casual or elegant depending on how you serve them. A while ago, a friend invited me to a Christmas party, and I particularly liked one of the appetizers: smoked salmon with goat cheese mousse. She served the mousse in glasses and topped them with chopped smoked salmon. What a great idea! In my version, however, I used cream cheese instead of goat cheese and served it in shot glasses. If you are going for something more casual, mix the smoked salmon into the mousse and serve as a dip.
