Been looking for a vid that explains this, it's so simple yet it never crossed my mind, never thought I'd find the answer in a 3 year old comment, thanks.
@SugarSwap I like your video thanks for posting. What type of soy sauce exactly did you pour over the omelette? It looks far too viscous to normal soy sauce. Thanks
Medium and low never works for me. My rule of thumb is within 10 seconds of dropping the eggs into the pan you should be able to start 'twisting' it. If it's still runny then the heat wasn't enough.and if it's cooked enough to stick to the pan then the heat was too much.
