This is a variation of regular chicken stock. It is very useful in many recipes calling for beef or veal stock. When you need a sauce for game, roast lamb or any dark sauce for a roast you can use this recipe.
The recipe is almost the same as regular light chicken stock with the main difference that you brown the bones, vegetables and add tomatoes, mushrooms and onion skins which all help to contribute color.
The rich brown color from caramelizing the vegetables and bones gives the stock a fuller and stronger flavor. One word of caution – do not add any ingredients that are black and burned as they will make your stock bitter.
When using dark chicken stock for beef, lamb, turkey or other meat, brown some scraps of that meat and simmer in the stock for added flavor as well as using pan drippings from roasts it is being used for.
You want the bones to be free from cartilage – then your stock is done.
It is a good idea to reduce some of your dark stock and freeze it in ice cube trays and store frozen in zip lock bags so you can pop a cube in your sauce to give it a lift.
