I am a new owner of a crock pot. I've wanted one for a long time now. This is the one reason why I finally took the 30 dollar plunge. Crack pot pho!
Other reasons are....
I like to make my own Chicken broth/stock.
Gas is too expensive to leave on a stove or oven for 4 hours.
More soupy delicious things to make for myself. Chili, chili cheese dip, beef stew, etc etc.
Finally can make pho
I've got to look up more recipes now, so I can figure out what things taste good in a crock pot. Personally, I'm just happy that I can make chicken stock without watching it and adding water every 30 minutes. I'm making a batch right now, but just with bones. We'll see how this one will turn out.
