A flatfish (plaice/sole family) gutted and sun-dried whole into a stiff, papery board, sold whole or as pieces and powder. Toasted in a dry pan or oven until fragrant, then simmered, it releases an intense clam-like savouriness that no other dried fish matches. It is the signature umami base of Cantonese wonton noodle broth and congee stocks, contributing depth rather than bulk.

In Cantonese food therapy it is used to open the appetite and lift the savour of the pot; fishermen prized it as a natural flavour-giver for everyday broths.
Toast it fragrant in a dry wok (白鑊) or the oven, then bone it and take the flesh; or toast it whole and put it in a soup bag.
