We used to have a dish called hash when I was a child. A sort of cross between a stew and a broth, with vegetables, and a traditional Yorkshire staple. That was made with shin and cooked very slowly on the hob - most of the day sometimes. I remember coming in from school in the winter to a cupful of the gravy to warm me up, and a slice of bread. Shin makes wonderful gravy.
Im aware of this, it is what the old fashioned ‘beef tea’ for invalides was rendered feom, but that wasn’t the question
I can only reiterate my perplexity that pp cannot or will not read understand and reply to the OP
