Not a recipe: beefy drink

I had half a beef Stockpot left over from yesterday and I won't be using it in a meal today so, to avoid wasting it, I popped it in a mug and half filled the mug with boiling water.  A quick stir and it made a warming, beefy, savoury drink that was a lot nicer than I expected it to be.  A little drop of marmite added would have been tasty too.

Stockpots are dear, but otherwise it would have been wasted so it was a frugal thing to do and I'm sharing.
