For actually dressing a salad, I'll take Ken's ranch, Marie's Creamy Italian Garlic, or a good Caesars.

But just as water is the universal solvent and O- blood is the universal donor, I also believe that ranch dressing is the universal dip.

Raw veggies - celery, carrots, broccoli. Fried mushrooms. Mozzarella sticks. Chicken wings (despite what the purists in the other thread say). Potato skins. Some may be better in blue cheese or marinara, but in a pinch, you can dip anything in ranch.

I was once visiting my then-girlfriend in St Louis, and even dipped my t-ravs in ranch. She was aghast (it may be part of why she eventually dumped me), but I thought it was pretty tasty.
