Is it good stock? Of course. I make it with chicken wings and thighs (and backs if I've saved some from cooking chicken myself) a couple of beef shanks (the marrow from the bones gives it additional body) carrots, onions and celery, black peppercorns, and tomato paste. It is to the box 'o stock as a really good hamburger is to McDonald's. I make it nearly salt free so I can control the amount of salt in whatever I use it in.
And yet, most of the time, I don't know that it makes enough difference to a dish to justify all the fussing, the straining, the pouring, the cleaning of the stock pot. I don't make my own tomato sauce for spaghetti. I can, but frankly, most of the time, my pasta sauce comes out of a jar. I don't make my own pasta most of the time. Again, I can, but it's just Bob and me. Granted, I will have this stock through the holidays. It will moisten my Thanksgiving stuffing, flavor may ox tail ragu for a Christmas party, make my weekly soup richer and better. But I could make a freeze tomato sauce, too.
I just like to make this stuff. I like the way it smells. I like the way I feel when I use my stock in something. I like the way the poor dogs mope around the house, driven to distraction my the scent. I like the way the house will smell when Bob comes home tonight. I just like it.
