This light yet creamy, ranch-style dressing is perfect for the tender, young lettuces of spring and early summer. If you want to add some crunch, it's tasty with trimmed radishes or slices of cucumber, too. Add them to a salad or serve the dressing as a dip. As long as you're using it as a dip, use this fresh, vibrant, homemade version wherever you might go for a bottled ranch dressing.
