Demi-glace

Demi-glace is a special sauce that is made by mixing two different sauces together. One sauce is made from animal bones and the other sauce is made from vegetables and herbs.

First, grown-ups take animal bones like beef or chicken and cook them in water for a long time. This helps create a liquid called stock. The stock is full of flavors from the bones.

Next, grown-ups take vegetables like carrots, onions and celery. They chop them up really small and cook them in a pot with herbs. This also helps create a liquid called a roux.

After that, grown-ups take the stock and mix it with the roux. They cook the mixture again so that it becomes thick and flavorful.

The final result is demi-glace which has a rich color and deep flavor. It is often used as a fancy sauce for meats like steak or lamb.
