Creamy Greek Salad Dressing - cooking recipe

Ingredients

1/2 tablespoon white vinegar or 1/2 tablespoon lemon juice
1/2 cup skim milk
1/2 cup olive oil
2 tablespoons red wine vinegar
1 teaspoon sugar
2 garlic cloves, minced
1 teaspoon dried oregano
1 teaspoon dried dill
salt and pepper
1/4 cup feta cheese, crumbled

Preparation

In a small bowl, combine the milk and vinegar or lemon juice. Let sit for 5 minutes. (This process will produce buttermilk. Alternatively, you can just use 1/2 c \"real\" buttermilk, but I use this method because I never have the real stuff on hand.).
Meanwhile, combine the remaining ingredients in a blender or food processor.
With the blade running, slowly pour in the buttermilk and blend just until thickened (if you over-blend, it will curdle).
Cover tightly and chill well before serving so the flavors have a chance to meld.
Dressing will keep for about 4 days (though it may need another whirl in the blender / food processor if it separates).
