grate turnip (I used food processor)
Turnip will create juice while grating, save it and add it to the rest water.
Saute the onion and shiitake mushrooms with olive oil for about 3 minutes in a pan.
Add grated turnip in the same pan and saute.
Add soy sauce, salt, white pepper powder until the turnip is done.
Mix water and the rice flour in a bowl and pour it into the same pan.
Stir constantly to prevent sticking on the bottom of the pan.
Turn off the heat when the mixture is think.
Pour the mixture into a suitable container for steaming.
Steam it for about 20 minutes.
Let it cool in the fridge for at least 2 to 3 hours until it is not soggy.
Slice it into for about 3 centimeters and fry it with 1 tbsp of olive oil before serving.
Serve it with the garlic sauce (simply whisk everything together).
