Peel the avocados and cut into cubes.  In a saut� pan, place the butter, wine, onions, garlic, thyme, and salt and pepper.  Bring to a light boil and add the avocados.  Allow this to simmer for about 15 minutes to infuse the flavors.  Add in the cream and capers and bring to a high simmer.  Stir often until reduced by half.  This is a great sauce for pork loin chops or any pork for that matter.  The peppery taste of the unripened avocados brings a subtle taste to the cream and the avocados soften to perfection.
