Oh and the name is from Bovine nothing to do with horses it’s a beef stock.
If thats directed at me then yes it is and originally was a beef product. I was just quoting the only section in wiki that showed its production method. Obviously it is made from beef boiled down to jelly paste.
Much of wiki quoted its uses throughout history, but failed to say how it was made.
eg Shackleton and his team about lived on the stuff for months, and while we know what Shakletons hut looked like, the info in wiki provides a clue of what it smelled like 😉
