*Crème fraîche goes by two other names: cultured cream and sour cream. True sour cream is a probiotic condiment. When sour cream is made from grass-fed fermented cream, it is a health food. Nancy's is one yogurt company that makes an organic, grass-fed, probiotic sour cream. When shopping for this ice cream, look for French-made crème fraîche, Nancy's sour cream or Green Valley Lactose-free Sour Cream ... or another organic sour cream that has these three or similar ingredients: grass-fed cream, probiotic and sea salt.
