Cut the beef, against the grain, into thin slices (about 2mm).
Put them into a mixing bowl. Add salt, Shaoxing rice wine, dark soy sauce, egg, cornstarch and water.
Rub and mix with hands until the liquid is absorbed.

Put romaine lettuce and bean sprouts in the same wok.
Fry with the remaining oil over medium heat until they lightly wilt.
Transfer to the serving bowl and set aside.

Turn the heat to medium. Add marinated beef, one piece at a time.
Simmer until fully cooked (no pinkness on the surface).
Pour the beef and stock onto the vegetables.

Notes
1. You may use any cuts of beef (except for some tough cuts for stewing dishes). I quite like thick rib which is an inexpensive cut, yet very flavourful and tender enough for this dish (when marinated properly).2. Choose dried chillies that suit your level of tolerance to spiciness. I use two types of Chinese dried chillies for this dish:
Facing heaven chilli (Chao Tian Jiao/朝天椒) which has a quite high heat level.
Lantern chilli (Deng Long Jiao/灯笼椒) which is mild in heat but very fragrant.
3. You may use regular red Sichuan peppercorns or the green variety. Please refer to my post “Sichuan pepper: your questions answered” to learn more about this unique Chinese spice.4. Sichuan chilli bean paste (Doubanjiang/豆瓣酱, aka spicy broad bean paste) is widely used in Sichuan cuisine and can be purchased in most Chinese stores. The best-known variety is Pixian Douban (郫县豆瓣) which needs to be coarsely chopped prior to cooking.
