You probably have your own egg-scrambling routine, which likely starts with butter in a hot pan. However, cutting that heat is another way to enhance scrambled eggs.
Using a cold pan simply means a pan straight off the rack sans preheating. This method allows for better temperature control, helping reduce errant, overcooked bits in the mix.
On preheated pans, eggs start to sizzle the second they hit the metal, keeping you on your toes to force the eggs to cook evenly. You can avoid this hassle with a cold pan.
Simply mix the eggs with salt and pepper or any other preferred ingredients. Then, add everything into a cold pan and gently stir over medium-low heat until done.
