Blue cheese dressing

Ok my kids absolutely love salad, and both want blue cheese dressing on it, so when I got an email with this recipe today I had to save it (don't have the yogurt to make it today). Can't wait to try it. The recipe calls for low fat buttermilk, and fat free yogurt, neither of which do I use (growing up on a dairy farm we had more fat in milk than whole milk so fat free stuff tastes funny, plus is WAY too processed).

Ingredients:

• 2 tablespoons mayonnaise
• 1/4 cup buttermilk
• 1/4 cup plain yogurt
• 1 tablespoon white vinegar
• 1/2 teaspoon sugar
• 1/3 cup crumbled blue cheese
• Salt and freshly ground pepper

Directions:

Fold a full sheet of paper towel into quarters and put it into a small bowl. Spoon the yogurt onto the paper towel and place in the refrigerator for 20 minutes to drain and thicken. In a medium bowl, whisk the buttermilk and thickened yogurt into the mayonnaise until smooth. Add the vinegar and sugar and continue to whisk until all the ingredients are well combined. Stir in the blue cheese and season, to taste, with salt and pepper.
