  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   1                    egg
     1/2  cup           onions -- chopped
   1      teaspoon      garlic -- minced
   1      teaspoon      salt
     1/2  teaspoon      ground red pepper cayenne preferably
     1/2  pound         blue cheese -- coarsely crumbled
   2      cups          veggie oil
     1/2  cup           buttermilk
   1      teaspoon      white pepper

Preparation:

In a blender, combine the egg, onions and garlic; process a few seconds until well mixed. With the machine still running, add the oil in a thin, steady stream; then add the butter milk and seasonings and process a few seconds more until well mixed, pushing the sides down once with a rubber spatula. Transfer mixture to a large bowl and add the cheese; mix with a metal whisk to bread up any large lumps, but leave the cheese somewhat lumpy. Refrigerate and sere cold on salad. Taste this for yourself, and add vinegar if desired. Donna/ North NJ Source: Paul Prudhomme's Cajun Louisiana Kitche
