2) Add water and bring it to a boil.
3) Add the rest of the ingredients except the fish (pls see note below).
4) Add Chinese cooking wine and oyster sauce.
5) Let it cook for about 15 minutes over medium heat.
6) Cover the lid and put the inner pot into the Thermos.
- The fish I used was grouper but it turned a tad too dry when I ate it, so I would recommend to either try cod fish due to its high oily content or add the fish in the morning.
