Have you ever had a shabu shabu? It's thinly sliced beef, pork, fish, tofu, veggies, and noodles sloshed around in broth to cook quickly and dipped in sauces. It is much like fondue without the cheese. The traditional sauces are Ponzu Sauce (I have two posted here) and Sesame Sauce. There are more sauces people use, but these are the original ones.
