WTF? You ask. This is streaky pork (五花肉/三层肉) made by my friend. Not so presentable but here’s the ingredient:
五花肉 Streaky pork
豆油 Soy Sauce
黑胡椒 Black Pepper
绍兴酒 Shaoxing Rice Wine
Again, it is tasty according to her. My family used to make this kind of dish (we called it Black Pepper Pork) but without the addition of rice wine.
