Tenshinhan is a delicious dish made up of a fluffy crab meat omelette served on a mountain of rice and then drizzled with a glossy sweet vinegar sauce. Not only is it extremely tasty, but it's super quick and easy to make too!
Simmer and stir occasionally until slightly thickened and glossy. Turn off the heat and leave it on the stove to keep it warm. (Reheat before serving if necessary.)
Add 1 tbsp of shiitake dashi (leftover water from the soaked shiitake) per serving along with Japanese mayo, grated ginger and a pinch of salt and pepper. Whisk well.
