I have been trying to do this for years and never got it. I gotta try this in my next stir fry.
A good pan helps enormously, too. I sacrificed a couple of eggs one day, trying to get the flip just right, but I ate the evidence, so no-one knew. It might even be good to try pancakes first, before you move up to an egg. When you can consistently flip a pancake, you can probably pull off an egg.
I always tell my friends to practice at their in-laws house so they don’t make a mess in their own kitchen.
