Kerrygold Pure Irish Unsalted Butter Made from cultured pasteurized cream, all Kerrygold butter comes from the milk of grass-fed cows that are free of growth hormones. This Unsalted version is an all-natural, cultured-cream Irish butter with a complex, nuanced flavor. Kerrygold Unsalted Butter has a higher butterfat content and is a perfect butter for baking. Youll notice its grass-fed cows milk richness when you bake for the first time and find your pie crusts are flakier and your cookies more delectable. And, in our humble opinion, there is no better butter for simply spreading on bread.
