How to Make It
Preheat the oven to 400 °. In a large roasting pan, roast the turkey parts for 1 1/2 hours, or until well browned. Transfer the parts to a large stock pot.
Set the roasting pan over 2 burners. Add 1 quart of the water and bring to a boil, scraping up the browned bits from the bottom. Add the liquid to the pot.
Add the onion, carrot, celery, garlic, salt and several pinches of pepper to the pot with the remaining 3 quarts of water and bring to a boil. Reduce the heat to moderately low, cover partially and simmer the stock for about 2 1/2 hours. Strain the stock and skim off the fat before using or freezing.
