Bring a large pot of water to a boil. Add a pinch of salt and a spoonful of vegetable oil to the water, so the broccoli will retain its nice color through cooking. Add broccoli. Cook until soft. Strain and place on a plate. ( see footnote 1)
While boiling the water, combine 1/4 cup water, the oyster sauce, the soy sauce and the sugar into a small skillet. Cook over medium heat until almost boiling. Turn to low heat. Cook until the sauce reaches desired thickness.
Drizzle the sauce onto the broccoli right before serving.
