Put the beef and beef bones in the oven and bake them thoroughly

Stir-fry miscellaneous vegetables (onion, celery and carrot) with tomato sauce until they are cooked thoroughly

Add appropriate amount of water, add miscellaneous herbs commonly used in western food, and cook them together with the baked meat and bones for more than 6 hours until the juice is concentrated. Use its name as the name of the sauce.

For example:

black pepper juice (cooked with chopped black pepper)

mixed fungus juice (cooked with mushrooms of various fungi)

onion juice (cooked with chopped onion or shredded onion)

garlic juice (cooked with chopped garlic)

red wine juice (red wine+boiled juice) < When cooking the juice, stir it constantly to prevent the sauce from getting burnt.

After cooking, season it with appropriate amount of chicken powder and salt, and add a little white wine.
