LOL these Youtube "experts"
Very few people like crispy eggs.
Let me teach you something. Even non-stick pans are not non-stick anymore after a year or so.
How to make any pan non-stick. Enamel, SS, Cast iron, old non stick.
Put a small bit of oil in pan on your stove and heat it at max. Make sure the oil cover everywhere. It can be really little oil and you can wipe it everywhere with a brush or your hand(before its hot). No need for a lot of oil running around in pan.
Now you heat it till it starts smoking, let it smoke at least 30s- 1min. It is better to use cooking oil than olive oil as its has a higher smoke point, but olive oil still work OK.
When it smoked your pan is now non stick. For fried eggs you can remove from heat and let it cool down a slight bit before adding eggs. Scramble eggs not necessary as you can stir before it get crispy and egg will cool down pan anyway.
This will never be as non stick as a fresh new good quality non stick pan, but close enough. I make scramble eggs(that stick way more than a normal fried egg) in the SS pan without anything sticking to the bottom.
And no butter wont work, it will burn. You can wipe a thin layer of oil, heat till smoke and then cool down a bit and add butter.
