Why do Scrambled Eggs Turn Green In a Cast Iron Skillet? This harmless but unappealing color change is the result of a chemical reaction between iron in the pan and sulfur in egg whites. Why do Boiled Eggs Turn Green? The discoloration that sometimes forms around the yolk of […]
A little splash of lemon juice when you are mixing the eggs up will prevent them from turning green.
While a seasoned cast iron pan is somewhat non-stick, its heat-retaining properties increase the risk of over-browning and overcooking your eggs -- pretty much the opposite of how you want a classic omelet recipe to turn out. This also makes gently stirring and flipping omelets a challenge.
The very best pan for scrambling eggs is a non-stick skillet because the eggs will slide easily without sticking to the pan. You can also use a cast-iron pan as long as it's well-seasoned (otherwise the cast iron can turn your eggs a greenish shade!).
What causes green spots on scrambled eggs? Green spots occur when eggs are overcooked for a long time (over 12 minutes) or at high heat. This is due to a reaction between the sulfur in egg yolk and iron in the egg white. The green color is due to the formation of iron sulfide.
The greenish ring occurs in eggs that are overcooked or cooled too quickly after cooking. While the color may look unappealing, the eggs have the same nutritional value and are safe to eat. The greenish ring is caused by sulfur and iron reacting on the surface of the yolk during cooking.
Salt the eggs when you scramble them and let them rest 15 minutes before cooking. They'll get a much deeper gold color.
Scrub off stuck-on bits: To remove stuck-on food, scrub the pan with a paste of coarse kosher salt and water. Then rinse or wipe with a paper towel. Stubborn food residue may also be loosened by boiling water in the pan. Dry the skillet: Thoroughly towel dry the skillet or dry it on the stove over low heat.
Your cast iron skillet needs to be well-seasoned in order to prevent sticking with scrambled eggs. You can tell if your pan is well-seasoned if other food you've been cooking has been lifting away nicely, and also by looking at it.
With proper care cast iron cookware can withstand a lifetime of use. Actually several lifetimes as these cast iron pans and dutch ovens are often passed down from generation to generation. Taking care of cast iron cookware is as easy as 1 – 2 – 3.
When eggs are cooked for too long, or at a temperature that's too high, a chemical reaction occurs. The sulphur in the egg white reacts with iron in the egg yolk to form iron sulphide, which gives the eggs a greenish grey colour, according to BBC Science Focus.
Use a Well-Seasoned Cast Iron Pan
A well-seasoned cast iron pan will cook up the perfect eggs every. single. time. If you're not sure whether or not your pan is seasoned well, or need to learn how to properly strip and season your cast iron skillet, check out our post.
After use, clean your pan with hot water and a soft sponge. Avoid detergents or scrubbers, as these are likely to take off the seasoning you've built up. Likewise, never place them in a dishwasher.
CLEAN CAST-IRON SKILLET AFTER EVERY USE
Wipe interior surface of still-warm skillet with paper towels to remove any excess food and oil. Rinse under hot running water, scrubbing with nonmetal brush or nonabrasive scrub pad to remove any traces of food. (Use small amount of soap if you like; rinse well.)
Eggs fall into the category of sticky foods that are not ideal for cast iron skillets that haven't built up their seasoning yet. While cast iron can become non-stick with sufficient use over time, a newer skillet will almost certainly cause your eggs to stick to its porous surface.
Common cooking oils like olive oil will gradually produce seasoning, but won't be as effective as grapeseed oil. Canola, other vegetable oils, and shortening are a little better.
I buy a giant thing of salt, and scrub any stuck-on stuff off with salt first. Pour a generous amount and add a tad of water to almost make a paste to help scrub stuff off. Then, I just use water to wash the salt off.
“When an egg is cooked for too long and/or at too high a temperature, the sulfur in the egg white combines with the iron in the yolk and creates ferrous sulfide, which has a green tint,” she explains.
The Secret To Fluffy Scrambled Eggs
The secret ingredient for perfectly fluffy scrambled eggs is whisking the eggs thoroughly and vigorously before cooking them. Whisking incorporates air, which produces fluffier scrambled eggs, and fluffy eggs are the end goal.
Even a little makes a difference. As cookbook author J. Kenji-López-Alt explains it in The Food Lab, adding water to scrambled eggs “means more vaporization occurs, creating larger bubbles in the eggs and lightening them.”
