Add cold water to the bones and mirepoix covering everything by about 2 inches.
Slowly bring the stock to a simmer over medium heat.
As the stock heats up, skim the surface periodically to remove any fat and impurities.
Cook the stock for approximately 4 to 6 hours.
About 30 minutes before the stock has finished cooking, add the bouquet garni of bay leaves, thyme, parsley and black peppercorns and continue to simmer.
Once the stock has finished cooking, gently remove the bones and mirepoix using a spider.
Strain the stock through a sieve lined with cheesecloth.
Ready to be used in soups, stews and many other dishes.
If not using immediately, cool the stock over an ice bath and store appropriately.
