Not whisking your scrambled eggs enough
If you don't whisk your scrambled eggs enough, you're probably not making restaurant-quality eggs. The key is to thoroughly whisk them in a bowl before adding them to the pan. The idea is that the whisking process creates air, which results in fluffy eggs.
Making cloud-like eggs may require more steps than you previously thought. Remember that even if you whisk your scrambled eggs thoroughly, you'll still need to remove them from the heat before they're fully cooked because they'll continue to cook in the residual heat. However, if you don't use a nonstick pan, you could follow this step and still not get the egg of your dreams.
