# Ultimate Guide to Eggs and Every Cooking Method

> Every egg cooking method comes down to one equation: **the whites set at 62 degrees and the yolks at 68**. This is the gap that makes soft-boiled eggs with runny yolks possible — and high heat closes this gap, resulting in rubbery eggs.

**4 min read**

Eggs are one of the cheapest and most versatile protein sources, yet a "boiled egg" cooked just the way you like it fails for most people. The reason is that the difference between one result and another is **one minute**.

## The Rule: Two Temperatures

The proteins in the whites and yolks coagulate at different temperatures:

  - **Whites:** Begin to set at **62 degrees**, and become firm at **65**.
  - **Yolks:** Begin to thicken at **65**, and become firm at **70**.
  - **Above 75:** The proteins shrink severely and squeeze out water — this is when the egg becomes **rubbery and dry**.

Each cooking method is basically an attempt to land at a specific point between these two numbers.

## Boiled Eggs — Timing Chart

Always start by **dropping them into boiling water** (not cold water) so the timing is precise and repeatable:

  - **4 minutes:** Barely set whites and completely runny yolk
  - **5 minutes:** Set whites and runny yolk (for ramen)
  - **6 minutes:** Creamy yolk in the center — the most popular
  - **7 minutes:** Soft, glossy yolk
  - **9 minutes:** Set but still moist yolk
  - **12 minutes:** Hard-boiled

**Transfer them to ice water immediately** after the time is up — this stops the cooking, prevents the **green ring** around the yolk (which forms from the reaction of iron and sulfur during overcooking), and makes peeling easier.

## Poached Eggs

  - Deep pot, water **not boiling** — just small bubbles (80 degrees).
  - **A tablespoon of vinegar** in the water — speeds up the setting of the whites.
  - **Strain the egg in a sieve** first to remove the loose outer white — this is the secret to a neat shape rather than a vortex.
  - Drop it from a cup close to the surface of the water.
  - **3 minutes** and remove it with a slotted spoon.

**Fresh eggs** make the best poached eggs — their whites are firm and don't scatter.

## Fried Eggs

  - **Medium heat** — high heat crisps the edges and leaves the center raw.
  - **Butter for flavor, oil for higher heat**, or both.
  - For cooked whites and a runny yolk: **Cover the pan for the last 30 seconds** — the steam cooks the top.
  - Salt the whites, not the yolks — salt on the yolk creates white spots.

## Scrambled Eggs

There are two schools of thought:

**French:** Very low heat, constant stirring, **10-12 minutes**. The result is **custard-like and creamy** with very small curds. Add a tablespoon of cold butter at the end to stop the cooking.

**American:** Medium heat, intermittent stirring, **2-3 minutes**. The result is **large, soft curds**.

**In both cases:** Salt **after** cooking — early salt draws out moisture and makes the eggs watery. Remove the pan from the heat **just before they are done** because they continue cooking with their residual heat.

## Frittata and Omelet

**French Omelet:** Medium heat, rapid stirring for the first 20 seconds, then let it set, and roll it while it is **still a bit moist inside** (baveuse). Yellow with no brown color at all.

**Egyptian Eguella:** Beaten eggs with parsley, onions, and vegetables, cooked on medium heat on both sides until browned. Thicker and more firm.

**Italian Frittata:** Starts on the stovetop and finishes in the oven, cut into wedges.

## Freshness Test

Put the egg in a cup of water:

  - **Sank horizontally to the bottom** = very fresh
  - **Sank but standing on its end** = a week or two, safe to eat
  - **Floated** = throw it away

**The reason:** The air pocket inside the egg grows over time as moisture evaporates through the porous shell.

**A practical trick:** Very fresh eggs are **hard to peel**. Therefore, keep the eggs you plan to boil as your **oldest** ones, and the freshest ones for frying and poaching.

## Storage

  - **In the original carton** on the middle shelf of the fridge — **not in the door** (temperature fluctuations).
  - The pointed end **facing down** — keeps the yolk centered.
  - **Do not wash them** before storing — washing removes the natural protective coating.
  - **Excess whites** can be frozen in ice cube trays for up to 6 months.
  - **Excess yolks** should be frozen with a pinch of salt or sugar (without them, they turn into a gel).

## Eggs in Baked Goods — Their Role

Eggs in cakes and baked goods are not just an ingredient — they perform four different functions:

  - **Structure:** Egg white protein coagulates with heat and holds the baked good together.
  - **Moisture:** An egg is 75% water.
  - **Emulsification:** Lecithin in the yolk binds fat and water — this prevents the batter from separating.
  - **Leavening:** Air trapped in beaten eggs expands with heat.

**And therefore:** Whites provide structure and dryness, while yolks provide richness and tenderness. A cake with extra yolks will be richer and softer, and extra whites will make it lighter and drier.

## Egg Safety

  - **Do not crack the egg on the rim of the bowl** — this pushes shell fragments and any bacteria on it into the batter. Crack it on a flat surface.
  - **Wash your hands** after handling raw eggs.
  - **An egg with a cracked shell** should be discarded.
  - **Recipes with raw eggs** (homemade mayonnaise, tiramisu) should use pasteurized eggs if you are serving them to children, pregnant women, or the elderly.

## Summary

Whites are 62 and yolks are 68 — all cooking happens in this gap. Start in boiling water and use a timer, transfer to ice water immediately, and salt scrambled eggs after cooking, not before.

## FAQ

### Why are boiled eggs hard to peel?
Because they are too fresh — the pH of the whites is still low so they stick to the membrane. Use eggs that are a week old for boiling, drop them into boiling water, transfer them to ice water for 5 minutes, and peel them under running water.

### What is the green ring around the yolk?
It is a reaction between the iron in the yolk and the sulfur in the whites caused by overcooking. It is not harmful, but its appearance and flavor are inferior. Avoid it by reducing the boiling time and transferring the eggs to ice water immediately after the set time.

### How do I poach an egg neatly?
Strain the egg in a sieve first to remove the loose outer white — this is more important than the vortex trick. Keep the water at 80 degrees (small bubbles, not a boil), add a tablespoon of vinegar, and drop the egg from a cup close to the surface.

### Can I freeze eggs?
Not in their shells. However, whites freeze excellently in ice cube trays for up to 6 months, and yolks need a pinch of salt or sugar before freezing, otherwise they turn into a gel. Raw beaten eggs can also be frozen.
