1. First, mix the duck meat with oil, tapioca and salt and leave it for some time.

2. Then wash the fresh shiitake mushrooms and red chili peppers and cut them into small pieces

3. Stir fry them at last. Put the red chili peppers in the oil first, then put the mushrooms, wait until the mushrooms are slightly browned and then put the duck meat to stir-fry. Add some water, smother it, and it's ready to go. (Because in the duck meat has been put salt marinade, so in the fried mushrooms can not put.)
