The same egg, seven different results. From rafadan to sahanda to omelet, each method has its own time, temperature, and secret. A practical guide to egg chemistry.

Cooking eggs looks like the most basic skill of the kitchen, but the results can vary widely. The same egg, on the same stove, in the same pan, can come out cream-soft one day and rubbery the next. The difference is usually a few small details about heat, time, and order. Each method asks for its own chemistry.
Before starting: three basic facts about eggs
How to tell if an egg is fresh. An egg dropped into cold water that sits on the bottom is fresh; one standing upright is one to two weeks old; one floating is past prime. As time passes, moisture escapes through the shell pores, the air pocket grows, the egg gets lighter. A very old egg (2+ months) is not eaten; a mid-age egg is better for boiling: the white's pH has risen, so it separates from the shell easily. For rafadan, a fresh egg gives a thicker white that holds its shape better.
Room temperature or out of the fridge? A cold egg is a problem for boiling and poaching: the shell can crack or cooking becomes inconsistent. Take eggs out 15-20 minutes before cooking. For scrambled and omelet too, a warm egg cooks more evenly in the pan.
Internal temperatures. Egg white sets starting at 62°C; the yolk passes a gel consistency at 70°C and fully sets at 77°C. These three values govern all the methods. The USDA's safe internal-temperature minimum is 71°C; at this value the salmonella risk in an egg practically falls to zero.
1. Soft-boiled egg (rafadan, 6 minutes)
White set, yolk runny. Eaten on its own, on a breakfast plate, on top of a salad, or in a ramen bowl.
Lower the egg into boiling water gently, boil hard 30 seconds, then turn the heat to medium-low. Set the timer to 6 minutes. When the time is up, transfer the egg immediately to an ice bath (ice + cold water), wait 2-3 minutes. This step stops cooking and helps the white separate from the shell.
Peel starting from the wide end, where the air pocket is. Peeling in cold water is easier.
2. Hard-boiled egg (katı, 11-12 minutes)
White and yolk fully cooked. A picnic classic, on salad, on top of menemen, a Turkish breakfast staple.
The method tested by Kenji López-Alt is built on starting by lowering into hot water. The common "start with cold water, bring to a boil together" method causes the white to stick to the shell. In an egg lowered into hot water, the surface coagulates quickly and separates easily from the shell.
Method: put water in a large pot, bring to a boil. Place the eggs in a strainer, lower into the boiling water, close the lid, after 30 seconds turn the heat to the lowest setting. Wait 11 minutes. When the time is up, keep the eggs at least 15 minutes in an ice bath, then peel.
The ice bath makes the white contract quickly; the rigid shell does not contract at the same rate, and a small gap forms between them. That gap makes peeling dramatically easier.
3. Poached egg (haşlama, without shell)
White cooked, yolk runny; a round form that holds shape on the plate. For eggs Benedict, on avocado toast, on salad.
The water is kept just at boiling (not a rolling boil, just a state where the surface bubbles, around 90°C). Add 1 tablespoon of vinegar to the water. Vinegar lowers the pH; the egg white protein coagulates faster, and the egg holds shape without falling apart. No salt is needed.
First crack the egg into a small bowl, then make a whirlpool by spinning the water with a spoon and gently pour the egg into the center of the whirlpool. The whirlpool gathers the egg around itself; it does not separate into pieces. Cook 3-4 minutes. The yolk stays runny, the outer white texture is set.
Lift out with a slotted spoon, place on a paper towel, clean the edges if needed. A fresh egg holds shape better; the watery white of an old egg disperses in the pan.
4. Fried egg (sahanda)
Classic "sunny side up" or "sahanda". An indispensable of the Turkish breakfast.
Heat the pan on medium, place butter or oil; when the fat melts and starts to puff, crack the egg. Add salt on the plate; in hot fat it crystallizes and leaves a mark on the yolk.
For those who want to brown the edges: turn the heat to medium-high, the oil should be hot. The edges brown like lace, the yolk in the middle stays runny. Cooking time 2-3 minutes.
For those who want the white fully cooked but the yolk runny: medium heat 3-4 minutes. If the lid is closed, the upper part also cooks from the heat, the yolk surface clouds. Without the lid, drizzle half a spoon of oil over the top; this "basting" cooks the yolk from above.
For single-sided cooking, watch out: if there is too little oil, the white edges burn; too much, the form breaks. A thin layer on the pan surface is enough.
5. Scrambled eggs (çırpılmış)
The difference between restaurant-quality creamy scrambled and home-style dry scrambled is just heat and movement.
The technique adapted from French cuisine by Gordon Ramsay starts with cracking the egg into a cold pan. Egg + butter go into the pan together beforehand; placed on the lowest heat. Stir 30 seconds, take off the heat, stir 10 more seconds, put it back. This on-off cycle is repeated.
Cooking the egg at low heat allows the proteins to coagulate slowly and evenly. At high heat the proteins form large curds; the liquid between them is squeezed out, and the result is dry. At low heat small curds form; they hold liquid between them, and a creamy texture is obtained.
Another detail from Ramsay: salt is added at the end of cooking. Adding salt to raw egg early denatures the proteins and changes the texture; raw egg moves to a watery form. Adding a spoon of cream (or crème fraîche) at the last minute stops cooking and enriches the taste.
Total time 4-6 minutes. When scrambled is plated, it should still look slightly glossy and moist. Take it off before it reaches a rubbery consistency; the residual heat finishes the job.
6. Omelet (French and Turkish styles)
The visual difference between two omelets is large; the technique is also different.
The French omelet does not take color; a soft yellow roll comes to the plate. The egg is whisked; a little salt is added. The pan is heated; butter is dropped; the pan is rotated so the fat covers the whole surface. When the egg is poured in, a fork stirs constantly; the pan is rocked back and forth at the same time. When the egg is still glossy and slightly liquid, the heat is turned off. The pan is tilted, the egg is gathered to one side, and as it is slid onto the plate it forms a roll. The process is 30-45 seconds.
The Turkish omelet is cooked on medium-high; the edges brown slightly; the top is cooked under the lid or by flipping. It is made with fillings like tomato, green pepper, sucuk. Time 3-5 minutes. The texture is firmer than the French omelet, more cooked, more breakfast-like.
A common rule for both omelets: the pan must be the right size. 20 cm for 2-3 eggs, 24 cm for 4-5 eggs. An egg spread thin in a large pan cooks fast and the texture comes out dry.
7. Baked / steamed (benmari or oven)
A less-known method in Turkish, it gives a creamy, delicate texture. The French "oeufs cocotte", English "shirred eggs", Japanese "chawanmushi" are made with similar techniques.
Simple bain-marie: in a small porcelain dish, a teaspoon of cream; crack an egg over it. Place the dish in a deep tray; pour hot water into the tray up to half the height of the egg dish. Bake at 180°C for 12-15 minutes. The white fully cooks; the yolk stays slightly runny.
On top you can add grated cheese, herbs, butter, or truffle. On French tables a classic brunch dish; in Turkish cuisine a steaming variation is seen inside a şakşuka or menemen pan (the lid is closed; the egg steams on top).
This method is ideal for preserving the fresh texture of the yolk. Unlike frying, the surface does not dry, does not puff; it stays creamy.
A closing note
Seven methods, seven different temperature curves. At the base of each is the same rule: egg protein cooks soft if it cooks slowly, firm if it cooks fast. Heat control, more than any single variable, is the actual decider of all methods. The person making the most mistakes with eggs in the kitchen is the one who picks the wrong heat and time, not the egg.
