All the ingredients appear.
All the materials should be shredded, so we can't be lazy. Don't be like me, the abalone mushroom just cut into strips, the taste is not good. Don't soak the potatoes in water, or they'll lose their starch and stick to the ham and the oyster mushrooms.
Add shredded ham and potatoes when you see them start to turn golden brown without any seasoning. Dish up the mashed potatoes as they soften.
Do not wash the pan, directly under the oyster mushroom stir-fry. Add the black pepper sauce, sugar and a little water. The black pepper sauce itself is salty, so don't overdo it. When the pleurotus eryngii is soft all the ingredients are poured together and stir-fried. You can adjust the flavor by yourself, the ham is salty, basically there is no salt in the dish.
A person to eat, put half of the ham is enough, a bit of a waste.
