There are two main brands of store-bought puff pastry available in the United States: DuFour and Pepperidge Farm. DuFour can typically be found in specialty food stores for more than double the cost of Pepperidge Farm. However, DuFour is made with all butter and has slightly better flavor and texture. Pepperidge Farm is made with shortening, but is significantly cheaper and available at practically any grocery store. While DuFour is the better product, I have used Pepperidge Farm on many occasions with success.
