Browned butter

Beurre noisette is a type of warm sauce used in French cuisine. It can accompany savoury foods, such as winter vegetables, pasta, fish, omelettes, and chicken. It has become a popular ingredient in other cultures as well, such as in contemporary American Italian cuisine or the traditional American chocolate chip cookie. It is widely used in making French pastry. It has a deep yellow, almost brown, colour and a nutty scent and flavour from the heating process.
