Many chefs prefer European Style butter because it makes flakier pastries, smoother sauces and more savory seafood, meat and vegetable dishes. The added flavor comes from additional fat content. Challenge European Style butter is Grade AA and is 83% butterfat versus 80% for regular butters. It is made by churning cream slower and longer in the age-old tradition of fine European butters. It has a creamier taste and a silkier texture. You can use European Style butter in place of regular butter in recipes for bolder, richer flavor.
