I made a chicken in the crockpot and ended up with some nice gelatonous stock that I cooled and poured into ice trays. I think I made some mistakes though, because I forgot to take off the fat before I froze. It made just short of one full ice cube tray worth of stock.
Anyway, I have a soup recipe that calls for 3 14.5oz cans of chicken broth and 2 cubes of bouillon. Is there a way I can use my frozen stock to substitute for some or all of this?
