Isaan-StyleWaterfall Beef Often called waterfallsalad, to me it’s tough to call this a salad. It’s more like a sauced steakwith spice and crunch from the rice powder served with fresh herbs. Isaan isthe Northeast region of Thailand that borders Laos. Dishes like larb andwaterfall salad have sister dishes in Laos and share a lot of common culture.If rib-eye seems too fatty, strip loin is also a great choice for this dish.
