Blue Cheese Dressing

This is a delicious blue cheese dressing for any salad. But while I like it on greens, I adore it on cold pear slices (either fresh or canned). An unusual palate pleaser.

1/4 cup wine vinegar
1/8 t. pepper
1/2 cup sour cream
1/4 cup crumbled blue cheese
1/4 t. salt
3/4 and 2 T. olive oil
1/2 cup apple sauce

Combine vinegar, salt and pepper in blender. Slowly add oil while running blender at low speed. Add sour cream, apple sauce and blue cheese. Blend until smooth.
