Use around eight chicken leg quarters. Make sure to clean and wash the chicken really, really well first. Pat them dry and place them in a very large stockpot. (Note: as all Lebanese moms do, she makes large batches for her large family and there's still leftovers for days. So, if you have a small family or don't want some leftovers for the freezer, I suggest you halve this recipe.)
Next, add in five or six dry whole bay leaves, four whole cinnamon sticks, seven or eight whole cardamom seeds, about a teaspoon or so of the whole black peppercorns and one large red onion cut into large chunks.
Add more than enough cold water to cover everything. The pot should be about ¾ full. Leave this uncovered to cook over high heat for about an hour and fifteen minutes. (If you halve this recipe, it'll only need about 45 minutes to an hour.) About halfway through, remove the fat off the top that has begun to form by using a spoon to spoon it out and discard.
After the cooking time is up, set up another pot. Pour your veggies into a large sieve to drain from the water. Pour the veggies into your new pot. Place the same large sieve over the top of your new pot. Use tongs to remove the pieces of chicken and set them aside in a large bowl. Carefully pour out the stock through the sieve into your veggie pot. You can also carefully ladle out the stock into the new pot. Just be careful because the stock will be very hot. The sieve will catch all the rest of the ingredients which you can discard.
