Bordier yuzu butter is a artisanal, lightly salted butter from Brittany, France, that combines the richness of traditional French butter with the bright, citrusy flavor of Japanese yuzu. It is made from the milk of free-ranging cows and has a velvety texture, with the yuzu providing a harmonious tartness that complements both sweet and savory dishes.  The butter is churned using a centuries-old process that includes hand-kneading with teak paddles to develop its distinctive quality, a method unchanged since the 19th century.  It is prized by chefs for its quality and is used for cooking, baking, or simply spreading on warm bread.
