Shui zhu yu, literally 'water-boiled fish', is one of Sichuan cuisine's great showstoppers. Don't let the name fool you — there's nothing plain about it. Delicate fish fillets are poached until silky in a mountain of bean sprouts and vegetables, then the whole bowl is drowned in a blazing hot chilli oil studded with dried chillies and numbing Sichuan peppercorns.
It looks dramatic (because it is), but the actual cooking is quite gentle — the fish is barely simmered so it stays tender, and all the fireworks happen at the very end when you pour sizzling hot oil over the chillies and garlic sitting on top. That sizzle is half the fun of the dish.
This is proper numbing, tingling, chilli-red Sichuan comfort food. Serve it with plenty of steamed rice to soak up the broth, and warn your guests it's spicier than it looks.
