1 1/2 c. sour cream
1/4 c. mayonnaise
1 pkg. Original Ranch Dressing Mix
1/2 - 1 c. blue cheese, crumbled

Mix sour cream and mayonnaise. Add Ranch Dressing Mix. Blend well, add crumbled blue cheese to taste. If mixture is too thick, add 1 tablespoon buttermilk. For milder flavor, especially if using as a vegetable dip, omit mayonnaise.
