I won't let bones go to waste. Any time I roast or bake, or even braise, I will save the bones and make a stock. So, last night, I slow cooked a chicken for "pulled chicken" and of course, save the bones, but my BF said, there is no point in making stock with bones that have been slow cooked. Really!! He says all the good stuff has already been cooked out,. So, is this TRUE!! It seems the stock I've made have in the past have been flavorful.
