Heat some butter or olive oil in the frying pan, and add eggs when warm.
Boil water in a deep frying pan, and add the egg.
Mix eggs in a bowl with some milk (or just water, if you prefer), salt and pepper, and chives (optional).
Heat in a frying pan on medium heat and flip over frequently.
Mix eggs in a bowl (same as above) and heat in a frying pan on low heat until done, so it stays together.
Put eggs in casserole filled with cold water, and heat up (if you put the eggs in the water after it has boiled, they crack). When the water boils, set the timer for 6-9 minutes, depending on how soft or hard you want the yolk (running yolk is usually 6-7 minutes).
