Demi-Glace SauceA classic demi-glace is a transformative tool to have in the kitchen. The smallest melts into a pan sauce and lifts ingredients without overwhelming a dish. A foundation that is both neutral and decadent – this is the achievement of demi-glace in French cookery. This rich, concentrated beef broth has been slowly simmered for a well-balanced flavour. Demi-glace is a classic ingredient in professional kitchens and can be used as the base for sauces. It can also be used to enrich gravies for meat or game, or simply add it to pan juices after cooking steak for an instant, well-flavoured sauce. Feel free to add butter! We use only organic grass fed beef bones.
