Memory is a big vague, but wash and clean the exterior of the beef bones with a small knife (there may be blood and veins that you need to scrape off). Put the bones on a baking pan and put it in the oven to bake until browned (30-60 mins depending on temp and type of oven) before using in soup stock pot. If beef brisket is expensive you can use less and add some ox tail instead. Bring to boil then immediately reduce heat to simmer. Scoop the foam/scum on top and stir the pot so stuff doesn't get burned on bottom.
