When you're looking for a new cast iron pan, you'll often come across two types: pans with smooth cast iron or rough cast iron. Both are true kitchen champions - they retain heat as if their life depends on it and can last for generations. But don't be mistaken: these pans differ quite a bit in texture. In this blog, we explain what these differences are, so you won't end up fumbling with the wrong pan in the kitchen.
What is smooth cast iron?
Pans made from smooth cast iron have a polished finish. During the manufacturing process, the pan is machine-treated after casting to remove any imperfections and the natural texture from the casting process. This results in a smooth surface that is ideal for seasoning your pan and gives it excellent non-stick properties. Due to this extra step, smooth cast iron is often a bit more expensive, but it's perfect for preparing dishes like eggs, fish, and pancakes.
Advantages of smooth cast iron
- Non-stick properties: thanks to the smooth finish, a well-seasoned surface becomes non-stick more quickly.
- Easy maintenance: the smooth surface prevents food from sticking, making cleaning easier.
- Visually appealing: the smooth finish gives a sleek look that is popular among chefs.
- Faster seasoning: the smoothness ensures that seasoning oil adheres evenly.
What is rough cast iron?
Rough cast iron has an unpolished surface that comes directly from the mould. Instead of being machine-treated, it retains the coarse texture created during the casting process. This makes it robust and ideal for intensive use, such as searing or grilling meat. Rough cast iron often requires a bit more maintenance, such as seasoning the pan to create a non-stick layer.
Advantages of rough cast iron
- Robust and durable: the rough surface makes these pans excellent for heavy-duty use.
- More affordable: the manufacturing process is less complex, making rough cast iron pans generally cheaper.
- Better adhesion during seasoning process: the seasoning oil penetrates deeper into the pores and grooves of the rough surface. This allows the oil to bond better and deeper, resulting in a more durable non-stick coating.
- Versatility: rough cast iron is less vulnerable to metal spatulas and high temperatures.
Smooth vs. Rough Cast Iron
| Smooth cast iron | Rough cast iron | |
| Finish | Polished, smooth | Rough, unprocessed |
| Price | More expensive | More affordable |
| Non-stick performance | Becomes non-stick faster with seasoning oil | Requires more seasoning oil |
| Cleaning | Easier | Sometimes harder with burnt-on food |
| Weight | Often lighter | Heavier due to extra material |
| Use | Suitable for delicate dishes | Robust uses like searing |
Which cast iron pan suits you?
Whether you choose smooth or rough cast iron, both types of cast iron pans are durable and versatile. Smooth cast iron offers convenience and a modern look, while rough cast iron is perfect for a more robust approach and intensive use.
