Saving all the odds and ends in the freezer while doing your daily cooking will give you an endless supply of stocks to cook with. You will not waste even those parts of the vegetables or meat that you paid for (usually by the pound), and will never again need to buy canned stocks. This will save you money and allows you to control the contents of your stocks. All the vegetables I have listed in the ingredients list are just ideas of things to save in your bag. You do not need each and every one of them to make a stock. Everything is optional. When you peel carrots or anything else, wash them first. It is rather difficult to wash peelings. I do not recommend strong flavored herbs like cilantro or vegetables that could color your stock strangely like beets. Note: In order for the recipe to post, I had to include measurements, but you don't need measurements. Just use what you have saved in your bags using more or less of whatever is there.
