can I make ...

Absolutely!

You can also save your chicken carcasses and any other meat bones in the freezer until you have a goodly amount and then simmer them to make the soup base and add the meat from a chicken joint.

The demand for stock must be increasing.. one local butcher is charging for chicken carcasses.  Then again, another refused to charge me and substituted a couple of duch carcasses as he had no chicken left when I last asked!

It's always worth asking for a carcass when you're in the butchers, as Mrs Ball says, even if you don't want to make stock that day it can always go in the freezer for later.

PS - why would you use a whole chicken and not just the carcass for soup/stock?

I always stock my carcass in the veg water after a roast & then freeze the stock to be used later for gravy or whatever I need. I also do the same with lamb & beef bones then I have the appropriate stock next time we have a lamb/beef joint.

Proper Jewish chicken soup (I have some Jewish ancestry) does start with a whole chicken, but then the meat is stripped off the bones and kept aside while the bones get a further simmering (extracts the calcium which is why the soup is reknowned for its health enhancing properties). You need really to get hold of boiling fowl though and I haven't seen one for sale for years now where I live  

The soup is strained of stock veg then you can either serve it as clear broth with the traditional matzo meal dumplings, which are cooked separately and added.  Or you can add more veg and simmer it, add the chopped meat back in and the dumplings and you have a complete meal in a bowl which will restore even the most jaded of spirits  

Meat and bones give a far richer stock than bones alone and this dish is so simple, it needs the extra oooommmph to make it special    Agree totally about being careful not to boil it Mrs Ball.  The slowcooker does a fine job at this  

Using the carcass, along with the usual stock veg and herbs, makes for the basis of a delicious soup/chowder and is well worth the effort.  I like the Jewish chicken soup too. It's lush but I generally make chicken and veg
