If using dried shiitake mushrooms, reserve the soaking liquid and use it in place of some of the water for extra depth of flavor.
Ensure the clay pot is properly soaked to prevent thermal shock when placed in the hot oven.
For a lighter version, you can reduce the number of potatoes or substitute with cauliflower florets.
Garnish with fresh chopped parsley and a drizzle of extra sesame oil before serving.
