I've watched "fried rice" experts on videos, on YouTube, and in person.
In person is definitely the best, for obvious reasons. You can ask questions.
The guy I watched in Cincinnati said to me that the "secret"is to use an insanely hot gas cooker. Yep - he had one; about twice the size of a kitchen gas ring. He put the wok on it and splashed in some oil.
Then he broke a couple of eggs into the oil, and moved them around at high speed for about 30 seconds.
In went the (cold, cooked) rice; again, lots of movement with the spatula.
He flipped the rice in the wok several times, occasionally scraping the contents with the spatula.
In less than 5 minutes, he served it.Perfect.
Unless you've got a really fierce gas ring in your kitchen, it's pretty difficult to copy "fried rice".
