Bottled Blue cheese dressing is simply awful, and making salad dressings is really easy. Make in small batches or larger, just make it! If you like this recipe see others at my website: mybestcookbook.wordpress.com
Mix everything except the milk,salt and parsley together and then add milk a bit at a time, until correct consistency is reached. Let sit in the fridge for a couple of hours to meld the flavors. It will thicken a bit, so you may want to add a dash more milk before serving. Will keep a good week.
