In a time characterised by the consumption of disposable products and microtrends, cast iron stands out as a timeless investment, promising generations of reliable service. This guide explores why cast iron cookware is not just a cooking vessel but an excellent addition to any kitchen.
What is Cast Iron?
Cast iron is a group of metal alloys primarily composed of iron (2-4% carbon), along with silicon and other elements. Unlike steel, it’s hard, brittle and resists bending. It’s made by melting iron ore and casting it into moulds. Its key characteristics include:
- Its high carbon content lowers its melting point and increases fluidity, making it easier to mould
- Its brittleness gives it high compressive strength but means it can crack under tensile stress, so it isn’t ideal for all structures or jobs.
- It is durable, strong and long-lasting, especially when protected from moisture.
- It has poor heat conduction but excellent heat retention, which means it heats unevenly but it retains and radiates heat very efficiently.
What is Cast Iron Cookware?
Cast iron cookware, including pots, pans, skillets, Dutch ovens and griddles, is made from cast iron poured and set into a mould. It is valued for the features listed above, namely its heat retention and durability. But these are not the only benefits of adding cast iron cookware or cast iron bakeware sets to your kitchen. So how else can they benefit you when used to cook and prepare food?
Benefits
Health benefits
Using cast iron cookware can boost your iron intake, a mineral necessary for maintaining healthy blood and overall energy levels. Unlike some modern non-stick options, cast iron does not secrete harmful chemicals into the food you’re cooking, making it a better choice for your health.
Financial benefits
Cast iron cookware, like a cast iron pot or cast iron pan, is generally affordable, particularly given its durability. With proper care, it can last for generations. Popular brands like Denby Cookware provide this strength. Their longevity ensures you won’t need frequent replacements, saving you money over time.
General efficiency
Cast iron cookware heats evenly across the surface, preventing specific spots from getting hotter and guaranteeing your food is uniformly cooked. If you season it properly, it is easy to clean and its heat retention means less time waiting for things to cook. This efficiency makes meal preparation quicker and more reliable.
Environmental benefits
The longevity of cast iron products not only provides financial benefits but can also have a lasting positive environmental impact. Relying on well-cared-for cast iron will reduce the amount you buy and bin, thereby reducing the amount of household waste.
Even if you choose not to keep the cast iron cookware or it gets damaged, it melts easily and can be reformed, which means it could be a potentially lasting recyclable material.
How to maintain it
How to clean cast iron
Clean your cast iron immediately after cooking using warm water and a gentle brush or scraper to keep it in optimal condition. Avoid soap, as this can strip the seasoning.
Make sure to dry the cookware completely (to prevent rust) and occasionally re-season it with a small amount of oil to maintain the non-stick surface.
How to season cast iron
Seasoning involves coating the cast iron with oil (vegetable, canola, grapeseed, etc) and heating it beyond its smoke point (approximately 232 degrees Celsius) until the fat polymerises. This process transforms the liquid fat into a hard, non-stick surface that the iron absorbs.
Should you replace your regular pots and pans?
Upgrading to cast iron cookware is a wise investment. It offers exceptional durability, nutritional benefits and efficiency. It delivers long-lasting performance, benefitting both you and the environment. If you choose to switch, you will reap these benefits daily and your cast iron will become a cherished staple of your kitchen collection.
