I am sorry about the pound of rice mixup. Lots of soup! I chose to leave out the rice altogether. Haven't a slow cooker anymore as I gave it to my son to take to uni with him. I used a heavy enameled dutch oven type of pot.
Sauteed the bits of meat on the carcass with a little pork belly, & , with cubes of carrot, celery, mushrooms, minced onion, a splash of white to deglaze the browned bits then s & p, 2 qts f water and let it cook with the lid on about 2 hrs. Oh and toward the end of cooking a handfuls of green beans, spinach, & a few peas & spring onion.
