Green Goddess Dressing

"Wonder if previous reviewer stirred ingredients together and served it immediately. I ran ingredients through food processor until homogenous and refrigerated overnight: Beautifully melded flavors! Excellent on the chopped salad with leftover grilled shrimp I made for brown bagging. Think it'll be good to dress roasted vegetables. That's another brown bag from Sunday supper leftovers. :) Really appreciate that (aside from the tarragon vinegar and the sour cream), all the ingredients are pantry staples--in my house, anyways. Thanks for posting this recipe!"
