There is nothing better than homemade broth. I have found it difficult to have all the leftover 'stuff' to make broth all at once. However, I have now found a way that works great and all you need is freezer space... Simply place all your veggie peelings and such in a freezer bag and freeze until you have the chicken/beef/pork bones and fat then just add the frozen veggie leftovers to a pot with the meat (or to make a vegetarian broth just wait until you have enough frozen vegetable leftovers. You can actually have a bag for meat and one for vegetables as well.
What tricks do you have for making homemade broth?
