Here is my super easy recipe for chicken stock:
Chicken bones, skin, fat, blood, ect (to acquire this, keep a bowl or bag in your freezer. When cooking chicken, place either cooked or uncooked chicken "waste" in the bag. When you have enough to fill your crock pot, get ready to make stock)
Vegetable peelings (you should not use vegetables that are rotting or gross. You can use things like carrot peels, celery leaves, onion and garlic paper, ect. Make sure to use mild flavored vegetables like carrots, celery, summer squash, baby turnips, mild greens like spinach, ect. You can save your veggie scraps in the same bag as the chicken parts)
One small onion chopped
2-3 peppercorns
Herbs (like parsley, bay leaf, celery seed, chive. Use small amounts and experiment)
Dump everything into your crock pot and turn to high. Add enough water to cover the chicken. You want the crockpot to be at least 3/4 full, or it won't run properly. I use a 3 quart crockpotand it holds one picked-clean chicken carcass, a cup or so of vegetable scraps, and a small onion. If you have a larger crockpot, I envy you. Use a larger onion and more scraps.
Cover, bring to a simmer, and let simmer for at least 8 hours or overnight. I like to start mine right before bed and leave running all night.
When done, turn crockpot off and remove lid. Let sit for 30 minutes or so, until the pot is somewhat cool.
Place a very large bowl in your sink and place a colander inside. Carefully (using good hot pads) dump the stock from the crockpot into the bowl. Pick up colander, and let drain for a minute. Press a large spoon against the cooked scraps until the remaining liquid is drained. Discard scraps (If you live in Seattle, you can add the scraps to your yard waste bin).
Place bowl in the fridge for several hours, until the stock thickens and the fat has solidified on the top. Using a large metal spoon, scrape off the fat . If you'd like, you can save the fat in a glass jar. Keep it in your fridge for a month or in the freezer for 3 months. It tastes fantastic on toast, or as the primary fat used in homemade french fries.
You can use the broth right away, or it will keep in the fridge for about a week. You can also freeze the broth. It should keep at least 4 months. I like to freeze mine in ice cube trays, which are about 2 tablespoons for each cube. I've also seen people freeze broth in their muffin pans, which are about 2/3 cup per cube. You can also freeze in plastic bags or containers.
I'll post pictures the next time I make broth.
Enjoy!
