Homemade Blue Cheese Dressing - Thick and Creamy

All-natural ingredients make this blue cheese dressing superior to anything you could buy at the store. It's wonderful on salad greens, of course, or you could use it as I often do -- as a dipping sauce for French fries, onion rings, crudité, and as a spread for a simple hamburger! Ingredients are listed below:

Homemade Blue Cheese Dressing
Ingredients for about 2 cups of sauce
1/2 cup buttermilk
1/2 cup high-quality mayonnaise
1 tablespoon freshly-squeezed lemon juice
1/2 - 1 teaspoon Worcestershire sauce
1 garlic clove, chopped (or 1 generous teaspoon garlic paste)

4-6 ounces blue cheese, crumbled
Fresh, minced parsley -- about 2 teaspoons, plus more for garnish
