Ingredients:

  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   1      medium        onion -- chopped fine
   4      tablespoons   butter or olive oil or comb -- or less
  10                    baked potatoes -- chopped coarsely
   1      quart         chicken stock
     1/2  gallon        milk -- any

Preparation:

Saute onion in butter or olive oil. Put onion and potatoes in food processor or blender. Add chicken stock. Pulse on and off. Add milk and process until desired smoothness. I like it slightly lumpy myself. You might find it easier to blend ingredients while cool and then reheat. Suggested garnishes: chopped green or red onion, bacon bits, grated cheeses (cheddar, roquefort, or queso anejo), red pepper flakes, tabasco, sour cream, virtually anything your heart desires.
