Inspired by a popular Vietnamese noodle dish, this is my Japanese version of it and the dish totally takes advantage of the unique versatility of the donabe steamer, Mushi Nabe. I can do steaming and simmering in one pot, and it makes a great presentation at the table, too. I also love serving it hot pot style, so you can cook a small batch of noodles to serve at a time and continue to cook and serve until done. Then, you can choose and enjoy different toppings for every batch, if you like. You can be creative and serve with a wider variety of toppings, too. The broth has layers of umami flavors with the dashi, reserved chicken juice and Ayu fish sauce. This dish is always so comforting and fun at the same time. Instead of serving with a sliced lemon, you can also try with a splash of Pure Hon-Daidai Citrus Juice. The bright aroma of the daidai citrus will completely upgrade the dish to another level!
