Fried Eggs Sunny Side Up
White and yolk are done at different temperatures: white sets at 62 °C, yolk thickens above 68 °C. That is why the heat stays moderate — turn it up and the white goes rubbery and brown underneath long before the yolk has warmed through at all.

What to use instead
Butter tastes better, but refined oil is more forgiving — if the pan has overheated, reach for oil instead.

Method
-
Step 1: Crack into a cup
Crack each egg into its own cup rather than straight into the pan. You will spot a bad egg before it ruins breakfast, and the yolk is far likelier to survive intact.
-
Step 2: Heat the pan
Set the pan over medium-low heat and give it two minutes. A cold pan sticks; a screaming hot one cooks the white unevenly.
-
Step 3: Melt the butter
Add the butter and swirl it over the base. It should sizzle quietly without colouring: browned butter tastes bitter here and leaves dark flecks on the white.
-
Step 4: Slide the eggs in
Hold the cup close to the pan and let the egg slip out. Dropped from a height the yolk is more likely to break and the white spreads into a thin overcooked film.
-
Step 5: Cook gently
Give them 3 to 4 minutes. The white should be completely opaque with no clear patches around the yolk, while the yolk stays domed and shiny.
-
Step 6: Salt the white only
Season the white, and only at the end. Salt on the yolk leaves white speckles and pulls moisture out of it.
-
Step 7: Serve on a warm plate
Lift them out with a spatula onto a warmed plate: on a cold one they lose their heat in half a minute and the yolk thickens.
Tips & variations
-
Tip
For a veiled yolk, add a teaspoon of water to the pan and cover it for 30 seconds.
-
Variation
For crisp lacy edges, fry in olive oil over medium heat and spoon the hot oil over the whites as they set.
-
Swap
Butter tastes better, but refined oil is more forgiving — if the pan has overheated, reach for oil instead.
-
Storage
None. A sunny-side-up egg lasts exactly as long as the yolk stays runny.
