Add the washed rice to your rice cooker.
Add water: place your fingertip on top of the rice and add water until it reaches your first knuckle.
Add the liquids: sesame oil, soya sauce, shaoxing cooking wine if using, and vegetarian oyster sauce. Mix.
Add the rest and arrange it on the top of the rice so that everything is submerged, but make sure it's on top of the rice!
Cook! If you have a fancy rice cooker (I just bought myself one for my birthday!) then use the "mixed" setting. Otherwise use the regular setting - you might need to add extra water and recook at the end if that's the case.
