Chicken Bouillon Cubes

4 pounds chicken wings and backs

2 carrots, peeled and cut into 2-inch pieces

2 ribs celery, cut into 2-inch pieces

1 leek (white part and 3 inches green), well rinsed and cut into 1-inch pieces

1 onion, halved

2 bay leaves

2 large sprigs parsley

1 teaspoon very coarsely ground black pepper

4 quarts water

1. Combine all the ingredients in a large soup pot or kettle and bring to a boil. Skim the foam as it collects on the surface. Lower the heat and simmer for 2 hours.

2. Strain the stock (you should have 9 to 10 cups). Return the stock to a smaller saucepan and bring it to a boil, skimming off any fat. Lower the heat and simmer until the liquid is a deep caramel color, syrupy, and reduced to about 1 1/2 cups, 2 hours. Turn the heat very low the last 30 minutes and keep a close watch.

3. Pour the reduced stock into an 8-inch square cake pan and cool to room temperature. Refrigerate, covered, until very firm, 8 hours or overnight.

4. Cut the stock into sixteen squares, and put into small snack size baggies. Freeze for future use.

Note: For a quick stock, dissolve 1 cube in 1 cup of water. Season with 1/8 teaspoon salt and pepper to taste.
