In my “celtic tigress” days I would have thought nothing of roasting a chicken, picking what meat I liked and then throwing away the carcass.  It’s far from throwing away the carcass I was reared and my mother still makes her own stock from roast chicken which I now do as well. If I’m careful 1 medium chicken will do us for 3 meals and if I have potatoes left over from dinner it also makes a batch of my potato scones.
