Making stock involves simmering animal bones, meat, chicken, or vegetables in water or wine, often for an extended period. Traditionally, stock is made by simmering various ingredients in water. A newer approach is to use a pressure cooker. The flavor of the stock comes from the bone marrow, cartilage and other connective tissue.
Meat: Cooked meat still attached to bones is also used as an ingredient, especially with chicken stock. Meat cuts with a large amount of connective tissue, such as shoulder cuts, are also used. Mirepoix: Mirepoix is a combination of onions, carrots, celery, and sometimes other vegetables added to flavor the stock. Herbs and spices: The herbs and spices used depend on availability and local traditions.
