The authentic Sichuan Spicy Boiled Fish, i.e. Shui Zhu Yu, 水煮鱼, is quite complicated. Here I have a simple version using the spicy stir-fry sauce which takes much less time and gives very good and tasty dish. I have tried a lot sauces package, "Spicy stir-fry sauce(Wang Jia Du)" is the one I love most. You can easily find it in Asian grocery store. You can also use other sauce package.
