Use defatted home-made beef or chicken broth using organic free range beef and chicken if possible and for best results use the long skinny ice cube tray (the kind you use for sports water bottles).
Simple chicken broth recipe:
In the evening just before going to bed ----
Put whole chicken in crockpot and cover with filtered water
Turn on low and forget until morning.
Turn crockpot off -- let cool enough to handle
Strain broth and put in the refrigerator -- the fat will get hard and you can discard it.
Pour the defatted chicken broth into the ice cube trays and freeze
I feed these delightful treats outside because they are messy
LET THE FUN BEGIN!
Bone the chicken and make fresh home-made chicken salad for dinner (impress someone --maybe YOURSELF!)
Simple Beef Broth Recipe:
Use beef Shanks -- they are tough cuts of meat that are very tasty and excellent for soup and broth..... they have a round bone that makes the best and safest chew toy too.....
In the evening just before going to bed
Place shanks in the crockpot cover with filtered water
Turn crockpot on low and forget until the morning
Turn crockpot off and cool slightly
Strain broth and refrigerate so that any fat will float to the top and harden
Scrape off fat, fill trays and freeze.
Use the beef to make a stew or soup.

Yummy!
