I take the trimmings and cut them up into bite size chunks. I then take a big pot and add some oil and roast some minced garlic and some chopped onions in it until golden brown. I then add the chunked up pork trimmings and brown them. Next add water, cut up potatoes, some chicken bullion, fish sauce, cracked black pepper, maybe some sliced mushrooms. Becomes a super tasty soup to have with your ribs when the ribs are done.
