In a small saucepan over medium high heat, stir together all ingredients for the sauce. Bring the mixture to a boil, reduce heat and simmer for 1 to 2 minutes, stirring occasionally. Turn off heat and cover with a lid to keep the sauce warm.
Bring a medium pot of water, enough to submerge the gai lan, to a boil. Add the gai lan and boil for about 3 minutes. Drain well and transfer to a plate. Drizzle the sauce over the top of the cooked gai lan.
Serve and enjoy!
