I am not a purist. I am not going to play one on the Internet. I like spice packets, and I definitely like shortcuts--I do use store-bought chicken broth (a lot.)---but I also use my own broth when I have it on hand in the freezer.
--store bought rotisserie chicken carcass (see! shortcuts!) if you are gluten-free or have other allergies, read the ingredients on the package carefully. Costco clearly labels their chickens as gluten-free.
-- chopped onion
--bunch of celery
--2 cups or so baby carrots
--small bunch of green onions
--head of garlic
--3 bay leaves
--1 tablespoon Italian Seasoning
--6 cups of water
--put chicken carcass into slow cooker stoneware
--coarsely chop onion, celery, and green onion; place into crock with baby carrots
--peel entire head of garlic; dump in
--add Italian Seasoning and water
Close it up and cook on low for 8-10 hours.
Place on a small cookie sheet and freeze. Once the bags are frozen, they are small enough to be tucked in nooks around your freezer.
This broth has NO salt added. I am happy about this, but some people really like salt. When using a homemade broth recipe, taste the dishes you make and add salt as needed. The overall sodium content will be much lower.
