Start your pot with beef broth boiling while you continue with the next ingredients. Take half of the onions and the ginger in half and roast using a skillet or toaster oven. Once the cut sides are nicely charred and the other sides have a nice golden brown, place into the broth. Next, using a pan or skillet, toast the cardamom pod(s), cinnamon, star of anise and the cloves together until they get a nice toasted color to them -dark brown but not burnt. They will also become very aromatic. Place them into the pot. Add the Hoisin sauce and the Pho Beef Paste. Bring pot to a Soft Simmer. Soft Simmer=the water is moving and vapor is coming out but it's not bubbling very much if at all. Make note what time you complete this step -you will need to let it simmer for 3 hours from this point. While you're letting it simmer, you can begin prepping the other toppings.
