This is really a great recipe! Our kids and I fell in love with Pho during the month we spend in Hanoi. I have a few suggestions, though. The pho spice packet is hard to find, even in Asian groceries. I find mine at an Asian grocery that caters primarily to Vietnamese clients. The brand they suggested to me is “Old Man Gia Vi Nau Pho Bac.” It’s available on Amazon, too. It’s a packet of whole spices with a cloth bag. Pho paste, pre-prepared broth, or bouillon just isn’t the same. The second suggestion is to roast the beef bones and onion first to give it a traditional, smoky flavor. Just put the onion and beef bones on a baking sheet at 425 until they are browned.
