What is Cast Iron?
Cast iron is a mix of iron and carbon which can be molded and placed into a cast. It contains 2% carbon which is the main alloying element and 1-3% silicon. The melting temperature point is very low, making it a lot more useful than other metals. It is very rare that cookware made from cast iron will get damaged due to its high indestructibility.
Since cast iron is a mix of iron and carbon, it can be used on induction cooktops, as well as on electric and gas stoves.
What's Great About Cast Iron Cookware?
One of the reasons people are drawn to cooking with cast iron is it doesn't have a non-stick coating like Chemours, Teflon™ or other PTFE compounds. There's no coating to wear off, get scratched or putting potentially harmful substances in your body.
There are conflicting opinions as to whether PTFE is safe. In the past, Teflon contained perfluorooctanoic acid (PFOA) which was a potential health risk. Chemours nor any reputable chemical company uses PFOA in its coatings.
The American Cancer Society (ACS) states the main focus of concern is not whether Teflon and other non-stick substances cause cancer. The concern is with compounds such as PFOA and similar substances. DuPont no longer uses PFOA in the manufacture of Teflon™. ACS also states if one breathes in fumes from a Teflon-coated pan that was overheated, they might experience flu-like symptoms. [Cookware coated Teflon™ should not be heated above (500ºF). ] Other than this, they maintain any risk to humans using cookware coated with Teflon has yet to be proven.
Another great reason to use cast iron pots and pans is that they retain heat well. If you’re cooking something like a baked egg dish where the egg finishes cooking outside of the oven, it is ideal.
Cast iron pans can also be used to make pan pizza, sear meat, fry eggs, and sauté vegetables. If it is well-seasoned then less oil will be needed to prepare your food.
The cast iron skillet or pan is versatile as can be moved from the stovetop straight into the oven without having to worry about ruining it. They can also be used over a campfire.
Altough the cast iron skillet is the most well-known and often used, other cast iron pieces include grills, griddles, dutch ovens and cast iron woks.
