Beurre manié Beurre manié Beurre manié (French "kneaded butter") is a dough, consisting of equal parts of soft butter and flour, used to thicken soups and sauces. By kneading the flour and butter together, the flour particles are coated in butter. When the beurre manié is whisked into a hot or warm liquid, the butter melts, releasing the flour particles without creating lumps. Beurre manié should not be confused with roux, which is also a thickener made of equal parts of sometimes clarified butter or many other oils and flour, but which is cooked before use.

In the United States, 100% cocoa butter must be used for the product to be called chocolate. The EU requires that alternative fats not exceed 5%
