The moisture content in Plurg· is lower than that of conventional butter, while the butterfat content is higher. With its rich flavor and smooth texture, Plurg· provides even browning in cookies, produces a higher rise in cakes and blends seamlessly into batters. The butter is available salted, unsalted or clarified. For more information, call 800/535-5371.
