Beurremont's Butter de Tourage is an unsalted and cultured butter with 83% butterfat, made according to the traditional European method. This butter has no added flavorings or color, and can deliver a creamier butter flavor with its higher melting point.

Uses: Use up to 25% less Butter de Tourage in recipes than regular butter. Butter de Tourage is perfect for achieving a lighter, flakier croissant crust, and can be used for richer sautés, clarifications, and buttercream.
