Bonox is a beef extract. It is primarily a drink but can also be used as stock in cooking. It was invented by Camron Thomas for the Kraft Foods in 1918, and entered large scale production the following year. It is still produced by Kraft.
This concentrated beef extract is rich in iron, niacin and folate. It is a thick dark brown liquid paste which can be added to soups or stews for flavoring and can also be added to hot water and served as a beverage.
