This dish is a famous Shanghai-style dish. To get the best flavour and texture, try to find the smallest and freshest freshwater shrimp. Enjoy with freshly cooked rice.
Live freshwater shrimp can be found in some Chinese/Oriental speciality markets or fishmongers (you may need to place a special order for them). If unavailable, use the smallest, freshest prawns you can find. Shaoxing wine can be purchased in Chinese/Oriental speciality shops. Alternatively, you can use dry sherry.
