I like to make my own broth / stock, mainly because I know what goes into it. It is even better when I can do it with farm fresh meats. I will usually make a bit of different kinds of broth / stock and store them into my freezer, sealed as that way I do not have to worry if it is gluten free or not (and not get myself and my daughter sick), nor do I have to worry about anything that may be in the stock.I know that I have at least 10 cups of each on hand in my freezer, and by cooking a roast you can easily save the juices and make your own stock.
