Tips about taking the silken tofu out of box without breaking. Use a small knife and separate the edges of the package. Take a plate and cover it over the package. Turn it over and then cut small holes on the two diagonal corners. Blow some air in, then the package can be removed easily. Remove the silken tofu out of the box and cut into small cubes around 10 cm wide.
Mix light soy sauce with sesame oil and a very small pinch of sugar in a bowl. Chop fresh green onions too.
Let the tofu block stay for a while and then it will release some water content out. Use a kitchen paper to remove the water carefully. Try to avoid moving the silken tofu, otherwise it might be broken very easily. Then add the sauce and top with green onion. Serve directly!
