Butter is one of the best and most famous products made in Normandy (second only to calvados, perhaps!). Norman cattle is a special breed raised for dairy, and they get to roam the tasty Normandy marshlands for nutrient-rich forage. Their milk is heavy and smooth, and the resulting butter is so sweet that it's tempting to eat it by the spoonful.
Butter-rich brioche is thought to originate in this region. Crêpes and rustic fruit-topped galettes are also common. And of course, there's nothing wrong with simply spreading some Normandy butter on warm baguette and calling it good.
Here in the U.S., look for imported brands of Normandy butter like Isigny Butter, Buerre de Baratte, and Président. Whole Foods and specialty import stores are your best bet for where to find them.
