Don't forget to roast those bones and any veggies (with skins & peels left on) before adding to the pot. Also add a good splash of ACV (apple cider vinegar). About 1 tablespoon per gallon of water. Don't worry you won't taste the vinegar and it will help break down the bones and leach out all those good minerals, And yes about the skins & peels of the veggies, that includes the onion & garlic skins too. Just give them a good rinse of any dirt & debris.
Chicken bones??? You can use either or both raw & cooked bones (that includes for the beef as well) so every time you have chicken for dinner, save those bones. Also, buy whole body chickens at the store and cut them up and/or debone them yourself. I do this and make several piles.....one for the wings, one for boneless breasts, one for leg quarters and another for broth bones, this includes the wing tips, necks and the body. I also save the bones after we've eaten as long as the seasoning used wasn't too wild cause it will flavor the broth......and/or check at a butcher shop for necks & backs & feet if they have them.
Another good tip..........if you do buy the whole chickens and debone them yourself.........pull off the skin and trim off all that fat. Then render it by cooking the oil/fat out of it till the pieces are crispy. Officially rendering it is to add some water to cook it, until the water evaporates/cooks off and you have what is called Schmaltz (chicken fat), that is good to cook with in place of oil or shortening and adds a little flavor, but does have a low smoke point. Those crispy pieces are like pork rinds sold as snacks if you add salt......but are also a great dog treat as well.
What Is Schmaltz?
If you want to make some of your own, ask your local butcher for chicken fat and skin, as they often reserve some when breaking down poultry. (You can also DIY this part with skin-on cuts of chicken if you prefer.) Once you have enough fat and skin — you'll need 3 to 4 cups of skin and fat to work with — add it to a large pot and cover with water. You can also add a quartered onion to the pot for added flavor, but it's not required. Simmer the mixture over medium-low heat until all of the water has cooked off and the fat begins to turn golden-brown.
Once the fat is rendered, strain it out with a fine-mesh sieve. (Pro tip: Reserve any crispy skin that results as a delicious, crunchy topper for pasta, salads, and veggies.) Store the schmaltz in an airtight container in the fridge for up to two weeks.
It's a Jewish thing I guess, but it's definitely a good way of using all of what you have to make something else. Anyway, it lasts longer than just 2 weeks
