🧈 Taste Bordier Butter

Visit the original shop for artisanal butter made from fresh, local milk. A true Breton delicacy! TikTok

We’re absolutely in love with Bordier Butter that we went to the original shop in Saint-Malo, France (2.5h from Paris)! 🧈❤️ Made from the freshest organic milk from local farms in Brittany, Normandy, and Pays de la Loire, every block feels like a piece of art. Watching the artisans slap that block of butter into shape is a feast for the eyes is such a treat. Make sure to turn your sound on to hear...
