Cut top sirloin steak into thin strips (see How To Easily Cut Beef Into Strips section above).
Place cornstarch into a bowl. Working with a few beef strips at a time dredge in cornstarch. Seperate dredged beef strips into 3 batches.
Heat a large frying pan with oils over medium high heat. Oil is ready to fry when tiny bubbles appear around tip of wooden spoon or chop stick. This will take about 2 mins (see section above in post for more details).
Working in batches, fry beef strips until crispy brown, about 3-4 mins per side. Carefully remove beef strips onto a paper towel lined plate and repeat with remaining 2 batches.
Whisk together ingredients for sauce.
In a seperate large frying pan or wok add sauce and heat over medium/high heat until sauce start to boil. Add in all of the cripsy beef strips and toss until well coated. Serve immediately over rice. Garnish with sesame seeds or diced green onions.
