Indio, California: As promised, here is my recipe for the creamiest blue cheese salad dressing you can make at home - or in your RV.

1/2 cup mayonnaise (I use Best Foods/Hellman's)
1/2 cup buttermilk
1/2 cup sour cream
1/2 cup crumbled Blue Cheese (I use Rogue Creamery)
1 Tablespoon white wine vinegar
1/2 teaspoon garlic powder
1/4 teaspoon Kosher salt
1/2 teaspoon ground black pepper
2 Tablespoons finely minced fresh Italian flat-leaf parsley
Mix all ingredients in a small bowl. Stir well to combine. Let rest at least two hours before serving. Keeps one week, covered and refrigerated. Makes two cups.

Until my next update, I remain, your cheesy correspondent.
