Lots of stuff out there about making homemade chicken stock. Why are you here when you could be on “the Google?”
First rule of chicken stock: you have to save chicken bones (in a zip-loc bag in the freezer).
Second rule of chicken stock (with exception discussed below): do not let it boil or it will never clear.
Third rule of chicken stock is: You can make a small quantity and add it to your next batch along with water.
Exception: you can boil the bones for a few minutes, then discard the water with the scum and start over. Chicken stock will take at least 1 1/2 hours.
A basic “power of two” stock: A whole chicken, or enough bones + wings + giblets to make a good stock. Two halves of an onion, two carrots, two celery stalks, two handfuls of parsley, two bay leaves, two sprigs thyme (not for me), two spices (salt and pepper to taste), two quarts water (=water to cover), two hour simmer (if you use a whole chicken, you can pick the meat off the bones and reserve it for other purposes).
Additional power of two additions: two cloves garlic, two finger sized sprigs of fresh dill, two parsnips, two halves of a turnip.
Listified, think of it this way (in my own oder of preference, and half the time I don’t have all the ingredients):
Bones
Salt and pepper
Onion
Bay leaf
Carrots
Parsley
Celery
[Thyme]
[garlic]
[parsnips]
[dill]
[turnip]
Simmer (emphasis on simmer) and skim any scum. Give yourself two hours minimum. It’s that easy. You can also throw in pork bones from your last bbq, or shrimp hulls, or turkey bones, or fish heads, or whatever. I strain my stock through a sieve lined with the cotton remnants of an old T-shirt. Cool to kitchen temperature, refridgerate, and skim off any fat that collects on the top the next day.
Again, it is that easy, and totally worth it.
