Break your four eggs into a bowl, add in a pinch of salt and then use a fork to whisk them together making sure the yolks are broken.
Heat a non-stick pan over a low flame. Melt the butter in the pan then spread it around by tipping the pan from side to side.
Pour in the eggs and wait a few seconds to let a thin layer of egg set on the bottom then gently use your spatula to push the eggs into the centre letting the raw egg spread out to the sides again.
