Cast iron's high emissivity means it cooks food above its surface, not just the parts in direct contact with the metal
Cast iron cookware has been a popular choice for many years due to its durability and longevity. It is also a good source of iron supplementation for those who may be deficient. Cast iron skillets, pots, and pans are versatile and can be used on various heat sources, such as stovetops, ovens, and open flames. They are also affordable and easy to maintain.
One advantage of cast iron cookware is its high emissivity, which is the ability of a material to expel heat energy from its surface. Stainless steel, for example, has a low emissivity of around 0.07, meaning it does not emit much heat energy, and only the food in direct contact with it gets heated. In contrast, cast iron has a high emissivity of 0.64, which means it radiates a significant amount of heat energy. As a result, when cooking with cast iron, the food above its surface also gets cooked, not just the parts in direct contact with the metal. This makes cast iron ideal for searing steaks and frying potatoes, as even heating is essential for these cooking techniques.
To achieve the best results with cast iron cookware, it is important to preheat it for at least 10 minutes, rotating it occasionally. Alternatively, it can be heated in an oven for 20 to 30 minutes. While cast iron is durable, proper care is still necessary. Regular cooking enhances the seasoning of cast iron, but certain foods and cleaning methods can affect this seasoning. For example, cooking highly acidic foods in unseasoned cast iron can cause the metal to leech into the food, affecting its flavour and potentially causing health issues over time. Therefore, it is recommended to avoid long-simmering acidic dishes in cast iron cookware.
In conclusion, cast iron cookware's high emissivity means that it cooks food above its surface, not just the parts in direct contact with the metal. This property, along with its durability and versatility, makes cast iron a valuable addition to any kitchen. With proper care and maintenance, cast iron cookware can last for decades and even be passed down through generations.

Grease gets hotter quicker in cast iron than in stainless steel
Cast iron is also a poor conductor of heat, so it more easily converts to heat energy. With induction heating, the heat is directly inside the pan, instead of the heating element, which allows for various losses (infrared and convection in the air). This means that cast iron can heat up faster and cook things more quickly and evenly.
Additionally, cast iron holds on to heat better than other materials. For example, while a stainless steel pan might lose 100 imaginary heat units per minute, a cast iron pan might only lose 95. This means that after ten minutes, the cast iron pan would be at 150 heat units, while the stainless steel pan would only be at 100.
Cast iron is also excellent at transferring heat, so not just the bottom of the pan gets heated, but the entire pan. This can contribute to faster cooking times, as the heat is more evenly distributed.
However, it's important to note that cast iron takes longer to fully heat up and cool down compared to other materials. It's recommended to preheat a cast iron pan for at least 10 minutes before cooking. Despite this, cast iron cookware is still a popular choice for many due to its durability, longevity, and even heat distribution. It's also a natural source of iron supplementation for those who may be deficient.

Cast iron is a healthy alternative to non-stick coatings like Teflon, which can be harmful to health
While cast iron takes longer to heat up and cool down, it has a high emissivity rating, meaning it expels a lot of heat energy from its surface. This means that when cooking, you are not just cooking the surface of the food in contact with the metal, but also a good deal of food above it.
Cast iron is a healthy and safe alternative to non-stick coatings like Teflon. Teflon is a synthetic chemical made up of carbon and fluorine atoms, also known as polytetrafluoroethylene (PTFE). Non-stick coatings are synthetic products containing various chemicals, and there is always a potential health risk. Inhaling PTFE fumes may cause body aches, headaches, chills, fever, and chest discomfort.
Teflon used to contain perfluorooctanoic acid (PFOA), which has been linked to health issues including chronic kidney disease, liver disease, thyroid disorders, testicular cancers, low birth weight, and infertility. While PFOA is no longer used in the manufacturing of Teflon products, there are still concerns about the potential health impact of other ingredients in Teflon products, such as PFAS (per- and polyfluoroaklyl substances). Research is ongoing to understand the nature of these ingredients and their impact on the human body.
Cast iron, on the other hand, is a natural supplement for you and your family. Most foods made in cast iron will benefit from a bit of iron being infused during the cooking process. This is especially valuable for those with iron deficiency and anaemia. However, it is important to note that cast iron should not be used to cook highly acidic foods, as this can cause the metal to leech into your food, giving it an off-flavor and potentially causing health issues.

Cast iron is durable and long-lasting, making it a one-time investment
Cast iron cookware has been a popular choice for many years due to its durability and longevity. It is a one-time investment that can last for decades, and even a lifetime if properly cared for. Cast iron is known to be incredibly durable, and with proper cleaning and maintenance, it can be restored to like-new condition, even if it has been neglected and left to rust.
One of the key advantages of cast iron is its high emissivity, which refers to its ability to expel a significant amount of heat energy from its surface. This means that when cooking, you are not just heating the surface in contact with the metal but also cooking the food above it. This makes it ideal for searing steaks, as it provides even heat distribution. Additionally, cast iron skillets are versatile and can be used on various heat sources, including stovetops, ovens, and open flames like campfires. They are also suitable for a wide range of cooking techniques such as searing, frying, sautéing, poaching, and broiling.
Cast iron cookware is easy to maintain and clean. While some people avoid using soap and abrasive sponges due to concerns about damaging the non-stick seasoning, a small amount of soap and a gentle scrubber are usually sufficient for cleaning. Proper cleaning and maintenance of cast iron cookware are crucial to prevent rust and maintain its non-stick properties. Regular cooking enhances the seasoning of cast iron, and certain foods, such as acidic dishes, can wear down the seasoning more quickly. Therefore, it is recommended to season and reseason cast iron generously and at the right times.
Cast iron cookware is a healthy and safe alternative to non-stick coatings made with polytetrafluoroethylene (brand name Teflon). Non-stick coatings contain synthetic chemicals that can pose potential health risks if inhaled. In contrast, cast iron provides a natural non-stick surface when properly seasoned, and it can even be a source of iron supplementation for those who may benefit from it. However, it is important to note that cast iron cookware may not be suitable for cooking delicate foods like eggs or fish, especially if the pan is not well-seasoned.

It is also versatile and can be used on any stovetop, including gas, electric, and induction. This makes it ideal for those who may move house and change from one type of stovetop to another.
Cast iron can also be placed directly into the oven, just like a baking dish, and can withstand temperatures of up to 500°F (260°C). It is perfect for baking dishes such as cornbread, a popular choice for cast iron. It can also be placed over an open flame, making it a great option for campfire cooking. Its versatility in this regard is another reason for its enduring popularity.
Cast iron is a good heat conductor and has a high emissivity rating, meaning it expels a lot of heat energy in the form of radiation. This means that when cooking, you are not just cooking the surface of the food in contact with the metal, but also heating a good deal of food above it. This can speed up cooking time, but it also means cast iron takes a while to fully heat up and cool down.
Cast iron is a healthy and safe cooking option. It can infuse food with iron, providing a natural supplement for those with iron deficiencies. It is a good alternative to non-stick coatings, which may contain harmful chemicals. However, cast iron should be well-seasoned to prevent food from sticking and interacting with the metal. Acidic foods, in particular, can react with the metal, so these should be avoided or cooked in enameled cast iron.
