Add ingredients to a large stock pot (I use the steamer insert so I can easily remove the scraps at the end) and bring to a boil. Reduce heat to a simmer and cook about 90 minutes or until broth is flavorful and aromatic.
Separate the scraps from broth by pouring through a strainer (or remove steamer insert from the pot to separate). Transfer broth into jars and store in the fridge or freezer. Scraps can be composted or discarded.
