This may be obvious, but whenever we buy a whole chicken (which is at least 2x a month) we cut it up and throw the back and neck into a ziploc bag in the freezer. Nobody actually likes eating the back, right? I think there are 8 backs in there right now, languishing while I wait for a cool day to make stock (not while temps are above 70, I'm a heat wimp, which is why I was so happy to move to Portland). Also, I hate to say this, but the sort of stock you made isn't really suitable for traditional Chinese cookery, which calls for a nice clear, delicate stock without browned chicken overtones. Of course, you may know this and just prefer the heavier taste, but when traditional recipes call for stock, it's a very light clear one that is implied. Also, I tend to prefer adding my aromatics to the dish, not to the stock. I think the flavors get "muddy" quite easily and don't do well in the freezer, but then I refuse to eat anything that has canned onions or tomatoes in it either, so maybe I'm a snob! One last thing, go for the cleaver. We have a really great old Sabatier cleaver from way back when they did hand grinding to sharpen and polish it. It could fell a small tree. It's not a Chinese one for meat, but French, with a lovely curve to the back so that all of your force is shifted downwards to the tip of the blade. It's great for doing any butchering. It's funny you want to hack duck to bits, the partner, who is ethnic Chinese, admires the western way of cutting fowl, with those huge pieces of meat and no bone bits! regards, trillium
