Whole chicken
Whole onion with 8 or so whole cloves stuck into it
Celery chopped
Carrots chopped
Bay leaf
Black peppercorns

Boil until done. Strain. Separate chicken meat, skin, and bones. Use the meat for whatever you want. Put the skin and bones back into pot, cover and simmer for about 2 more hours until the bones are really soft.

Pour the whole thing through a sieve, let all the broth drain out. Pour this broth into ice cube trays and freeze. When frozen pop out and put into a zip lock bag.

6 cubes = one can of chicken broth. Contains no salt.
