The iron alloy used to make these skillets is an excellent conductor of heat, allowing for consistent cooking results. Additionally, cast iron skillets can be used at high temperatures, making them ideal for searing meat, cooking vegetables, and baking cornbread.
The Ridges on Cast Iron Skillets
Now, let’s talk about the ridges on some cast iron skillets. The ridges, also known as “machining marks” or “manufacturing marks,” are a result of the manufacturing process. When cast iron skillets are made, they are often machined to create a smooth surface. However, some manufacturers may choose to leave the ridges intact, which can serve several purposes. The ridges can help with food release, making it easier to cook and clean the skillet. They can also provide a texture for cooking, allowing for better browning and crisping of food.
The Science Behind the Ridges
To understand why some cast iron skillets have ridges, we need to look at the manufacturing process. When cast iron skillets are made, they are first cast in a mold, and then they undergo a process called “machining.” Machining involves using a machine to remove excess metal and create a smooth surface. The machining process can leave behind ridges, which are a result of the tool used to machine the skillet.
The Machining Process
The machining process involves using a lathe or a milling machine to remove excess metal from the cast iron skillet. The machine uses a cutting tool to remove the metal, which can leave behind ridges. The depth and width of the ridges depend on the type of cutting tool used and the speed at which the machine operates. Some manufacturers may choose to use a finer cutting tool to minimize the ridges, while others may leave the ridges intact for the benefits mentioned earlier.
The Type of Cutting Tool Used
The type of cutting tool used in the machining process can affect the appearance of the ridges on the cast iron skillet. A rough cutting tool can leave behind deeper and wider ridges, while a finer cutting tool can produce shallower and narrower ridges. The choice of cutting tool depends on the manufacturer’s preferences and the intended use of the skillet.
Do Ridges Affect Cooking Performance?
The ridges on a cast iron skillet can affect cooking performance, but the impact is usually minimal. The ridges can help with food release, as mentioned earlier, which can make cooking and cleaning easier. However, the ridges can also retain heat, which can affect the overall cooking performance of the skillet. In general, the benefits of the ridges outweigh the drawbacks, and many cooks prefer cast iron skillets with ridges for their unique cooking characteristics.
Cooking with a Cast Iron Skillet with Ridges
Cooking with a cast iron skillet with ridges requires some adjustments, but the results can be well worth the effort. Preheating the skillet is essential to ensure even cooking, and using the right amount of oil can help prevent food from sticking to the ridges.

What are the ridges on my cast iron skillet and why do they exist?
The ridges on a cast iron skillet are a common feature found on many types of cast iron cookware. They are often referred to as “machining marks” or “mill marks,” and they are a result of the manufacturing process used to create the skillet. When cast iron is poured into a mold to create the shape of the skillet, it is then removed from the mold and undergoes a process called “machining,” where the surface of the iron is smoothed out using a milling machine. This machine leaves behind small ridges or marks on the surface of the iron, which are the characteristic ridges seen on many cast iron skillets.
These ridges serve several purposes, including providing a texture for food to cook against, which can help to create a crispy crust on the outside of dishes like seared meat or vegetables. Additionally, the ridges can help to distribute heat evenly across the surface of the skillet, which can improve cooking performance. The ridges can also provide a surface for oil and seasoning to adhere to, which can help to create a non-stick surface on the skillet. Overall, the ridges on a cast iron skillet are a natural result of the manufacturing process, and they can actually provide several benefits to cooking with cast iron.
Are the ridges on my cast iron skillet a defect or a design feature?
The ridges on a cast iron skillet are not a defect, but rather a design feature that results from the manufacturing process. Many people believe that the ridges are a sign of a lower-quality skillet, but this is not necessarily the case. In fact, many high-end cast iron skillets have ridges, and they are simply a result of the way that the iron is milled and finished. The ridges can actually provide several benefits to cooking with cast iron, as mentioned earlier, including improved heat distribution and a texture for food to cook against.
It’s worth noting that some cast iron skillets are designed to have a smooth surface, without ridges. These skillets are often referred to as “smooth-bottom” skillets, and they are created using a different manufacturing process that involves polishing the surface of the iron to remove any machining marks or ridges. While these skillets can be useful for certain types of cooking, such as cooking delicate foods that might stick to the ridges, they can also be more prone to sticking and may require more maintenance to keep them in good condition. Ultimately, whether or not the ridges on a cast iron skillet are desirable is a matter of personal preference.
Can I remove the ridges from my cast iron skillet?
While it is technically possible to remove the ridges from a cast iron skillet, it is not necessarily recommended. Removing the ridges would require using a significant amount of elbow grease and possibly some specialized tools, such as a sanding block or a polishing wheel.
