We prefer the flavor and texture of Tofutti Better Than Sour Cream. Other dairy-free sour creams will add their distinctive flavor and you may need to adjust the consistency with water. We strongly prefer our favorite vegan mayonnaise, Just Mayo. [Ed. note: see related article, "America's Test Kitchen finds a vegan mayonnaise game-changer."] This cilantro sauce is a perfect complement for our recipe for Baja-Style Cauliflower Tacos.
