I got this recipe from www.topsecretrecipes.com under Outback Steakhouse. I've always loved their ranch dressing and was so excited when I found this.
1 teaspoon Hidden Valley Ranch dressing mix (buttermilk recipe)
1 cup mayonnaise
½ cup buttermilk
¼ teaspoon coarse grind black pepper
1/8 teaspoon paprika (possibly substitute red pepper for paprika)
1/8 teaspoon garlic powder
Combine all ingredients in medium bowl, mix well. Cover bowl and chill dressing for at least 30 minutes before serving.
Makes 1 ½ cups.
I used cayenne pepper in place of the paprika and it came out great.
