Preparation of Beef Stock:

To make good stock you must put all the ingredients in cold water and bring to a boil. On the other hand if you want to boil meats you have to add it when the water is boiling.

Put water in a large pan, put in all the meat and vegetables and bring to a boil, let simmer on a low heat for at least 2/3 hours. Check the meat as it cooks from time to time. The stock should thicken.
