This is honestly a great and simple chip dip recipe that I got from a friend years ago, though I have made a couple little changes of my own. It is always a hit at get togethers. You'll never want store bought dip again!
In blender or food processor add cream cheese, onion, horseradish, garlic powder (to taste) and chives. Start to blend adding milk in small amounts until desired consistency. Add additional horseradish and garlic as desired. Chill a minimum of two hours before serving or over night.
