What is demiglace?

Demiglace is a rich, flavorful sauce made from a mixture of equal parts of brown stock and brown sauce that has been reduced by half. It is a classic French sauce that is used as a base for many dishes.

To make demiglace, first, brown stock is made by simmering beef bones for several hours with vegetables such as carrots, celery, and onions. Brown sauce is made by simmering vegetables and meat scraps in a roux made from butter and flour before adding beef stock. The two are then combined and reduced until thick and syrupy.

Demiglace is often used as a base for other sauces and is a key ingredient in classic French dishes such as boeuf bourguignon and coq au vin. It can also be used as a glaze for roasted meats or as a dip for French dip sandwiches.

While demiglace can be time-consuming to make from scratch, it is available in many specialty food stores and can be purchased online.
