Turn on the frying mode and heat the oil well.
Fresh broccoli to disassemble into inflorescences, frozen to defrost.
Fry with ginger and salt for 5 minutes (note that the oyster sauce is salty).
Add sugar.
Add the broth.
And oyster sauce. Stir and simmer in the same mode for another 5 minutes.
I want to note that the amount of this or that ingredient you can choose according to your taste.
