Did you know there really was a "Hidden Valley Ranch"? It was a resort in California, owned by Steve and Gayle Henson, the place where ranch dressing was invented. Steve Henson's simple mixture of mayonnaise, buttermilk and herbs has become our favorite way to liven up lettuce. However, commercially bottled ranch dressing is made with unhealthy soybean oil, then loaded with preservatives, artificial flavors and finished with a dose of monosodium glutamate, a known neurotoxin. This is far from what Henson served his guests at Hidden Valley Ranch. Let's return to the ranch and make our own healthy Ranch Dressing.
