Says Chef Eliot Barton of Mangia Mangia restaurant in Key West, "This is the only dressing available at Mangia Mangia." He recommends using high quality vinegars and olive oils and adds, "The little bit of water reduces acidity but retains the fine flavor of the vinegar. Inexpensive vinegars are already too diluted. Look for vinegars in the range of 6 % acidity." From "The Florida Keys Cookbook"
