Ranch dressing is the best-selling salad dressing in the U.S., surpassing Italian dressing near the end of the 20th century. Love it or hate it, it's ubiquitous and it's not just for salads. Ranch is now a popular flavor, and a dip for hot wings, fried pickles, and even pizza. This versatile staple is found in grocery stores, recipes, and on menus across the country. Steve Henson, a plumbing contractor turned dude ranch owner, created it in the 1950s, and it became a cultural phenomenon, inspiring a fandom and sparking debates.
