Reddit reviews Oriental Beef Spices (Gia Vi Nau Bo Kho), 2 oz. (56.7g) Bag, 2-Pack

The packaged spice will look like this. They aren't very expensive at the Chinese supermarkets, if you're around one. This is the type of noodle you should buy, this specific brand if you can. *To cook the noodles, have a pot of boiling water, dip the noodles in using a strainer for about 7-10 seconds, then take it out, straining the water as best you could.

I cube the beef (pretty big chunks) and it's a plus to have some fat leftover on the meat. Mix about 1/4th of the packaged spice with ketchup with the beef before you sear it. Once that's done, in the slow cooker, have water, beef broth, and about 1/2 the package of spices mixed in the slow cooker. Add the seared beef and cover for about 6 hours on low. At that point, you can add the potatoes and carrots (cut into slices) and it'll be done in about 1 to 1 1/2 hours. You can also get french loaves and dip it into the soup.
