Of all the types of margarine that are commonly available at a supermarket, Nucoa is the only type that is "true margarine", that is, it contains absolutly no dairy products, such as minute qualities of whey or milk solids.
Although it usually comes to twice the price of normal margarine, the use of Nucoa for Vegan, Ital and Kosher cooking is well worth the price, especially when you consider the value of a big plate of Vegan Chocolate Chip Cookies.
