This butter from Normandy is one of the most famous French butter in the world, boasting a tangy nuttiness and saltiness that gives it the savory essence of umami in every bite.
The distinct tangy flavor of the butter comes from the fermentation process. In French, "demi-sel" translates as "half salt," an important part of the butter's umami profile.
The real magic, however, comes from the "de baratte" portion of the butter's name, highlighting its hand-churned manufacturing process, using an old-fashioned wooden butter churn.
According to Elle & Vire, only about 10% of the butter produced comes from the hand-churned process, making this toast spread a rarity in the butter world.
The green grass and rich soil of the Normandy region also contribute to the butter’s flavor as it nourishes the cows. In other words, if the cows eat well, so do you.
