Steamed Chicken and Black Fungus in Brandy

This is the simplest steamed chicken recipe ever and my mother has been cooking this for us for ages. Just need to marinade 2 chopped up skinless chicken thigh (preferably free range/kampung) with a big dash of oyster sauce, a little sugar, white pepper, about 1 tsp of cornflour and a large dash of brandy :p Usually Tsao Tsing Chinese Cooking Wine is used but I've ran out. I have lots of brandy
