We tried the Clipstone‘s Sunday Arrosto, and they included a card thanking us (you’re welcome!) and also suggesting we could use the chicken bones for a stock. Why, of course! You don’t need to say that twice.
I immediately placed the bones and a few vegetables into my pressure cooker and had it extracting all the flavour that could be left for an hour. But then I was not quite sure what to do with the veggies because they had become a bit too mushy (specially the leeks).
