Torch Searing: Friend Or Foe To Cast Iron?

Using a blowtorch to sear meat in a cast-iron pan can be a great way to get an even crust. However, it is important to note that a blow torch may not be the best option for searing large cuts of meat, as the flame is too focused. A cast-iron pan can retain a lot of heat, giving a more even crust, but it can struggle with oddly-shaped pieces of meat. A blow torch, on the other hand, is great for searing uneven shapes and touching up spots that the pan may have missed.

Using a torch on a cast iron pan can lead to an uneven sear

Using a blow torch on a cast iron pan can lead to an uneven sear. The cast iron pan retains a lot of heat and gives a more even crust, while a blow torch is hot and direct but not as fast since you're working with a small flame. The cast iron pan is also better for searing evenly on flat cuts of steak or pork.

A blow torch is good for searing unevenly shaped meats and touching up spots that are hard to reach with a pan. However, it can be difficult to control the amount of heat applied and it can be slower than using a cast iron pan. A blow torch can also add a "torch taste" to the meat if the flame is not set correctly.

Combining the two methods can be useful for getting an even sear on both sides of the meat. Using a cast iron pan to sear one side and a blow torch to touch up the other side can result in a good crust and reduce the "torch taste".

A cast iron pan can be used on the grill, stovetop, or in the oven

A cast iron pan is a versatile piece of cookware that can be used on various heat sources, including grills, stovetops, and ovens.

When using a cast iron pan on a grill, it is essential to preheat the pan adequately to ensure even cooking. Cast iron pans retain heat well and can help create those desirable grill marks on your food. To enhance the grilled flavour, consider using spices like smoked paprika or smoked salt. Additionally, adding ingredients like fish sauce, anchovy salt, soy sauce, or hoisin sauce will boost the umami taste.

On a stovetop, cast iron pans excel at searing steaks and other meats due to their ability to retain heat. To achieve a good sear, preheat your pan over medium-high heat until it starts smoking. Then, add your steak and cook for a desired amount of time, flipping occasionally, until you get a nice crust.

Cast iron pans can also be used in the oven, and this method is particularly useful for restoring a rusty pan. Place the pan upside down in the oven and bake at 450-500 degrees Fahrenheit for about an hour. This process will help strengthen the seasoning on your cast iron, giving it a natural, easy-release finish.

Cast iron pans are a durable and versatile option for cooking, whether you're grilling, stovetop cooking, or baking in the oven. With proper care and maintenance, they can last for generations.

A torch can be good for searing unevenly shaped foods

A torch is a great option for searing unevenly shaped foods. The precision of a torch allows you to target specific areas of your food, making it ideal for searing unevenly shaped items. While a cast-iron pan can struggle with odd shapes, a torch can easily reach all areas of your food.

A torch is also a good option for searing foods with delicate textures, such as fish. The precision of a torch allows you to control the heat and avoid overcooking delicate foods.

Additionally, a torch is a useful tool for post-sous vide cooking. The low heat of a sous vide machine means that food often lacks a crispy exterior. A torch can be used to add a sear to your food without overcooking it, giving you the best of both worlds.

However, it's worth noting that using a torch can be slower than using a cast-iron pan, and it can be more difficult to control. A combination of both methods can be effective, using the cast-iron pan for most of the searing and the torch to touch up any uneven spots.

If you're considering purchasing a torch for searing, there are a few things to keep in mind. Firstly, look for a torch designed for "industrial" uses, such as soldering or welding. These torches can reach temperatures greater than 3,000°F, which is hot enough to sear your food effectively.

Secondly, consider the type of gas used in the torch. Propane is the most popular option due to its low price and adequate heat generation. MAP-Pro, a variant of propane, burns hotter but is more expensive. Butane burns cooler and is often used in smaller "kitchen" torches.

Finally, be sure to use proper torch technique. Adjust the flame to achieve a fully oxidizing flame, which is a dark blue, relatively short flame that hisses and roars. This type of flame ensures complete combustion, reducing the risk of unpleasant flavours in your food.

With the right torch and technique, you can easily master the art of searing unevenly shaped foods and take your cooking skills to the next level.

A cast iron pan can be used to sear multiple items at once

A cast-iron pan is a versatile workhorse and can be used to sear multiple items at once. Its high volumetric heat capacity means that once it's hot, it stays hot—ideal for searing meat. Its high emissivity means it expels a lot of heat energy, cooking a good deal of food above it. This makes it perfect for cooking several portions of meat, poultry, fish, or vegetables at the same time.

When searing with a cast-iron pan, it's important to ensure the pan is properly heated. Place it over a burner and let it preheat for at least 10 minutes, rotating it occasionally. Alternatively, heat it in an oven for 20 to 30 minutes. The key to pan-searing is a high temperature that creates the Maillard reaction—a chemical reaction that gives browned foods their distinct color and flavor. The Maillard reaction begins at about 285°F, so it's recommended to heat the skillet to at least 400°F before adding food.

When cooking multiple items in a cast-iron pan, make sure the pan is large enough to accommodate all the food without overcrowding. This will ensure even cooking and browning. Additionally, avoid moving the food around too much so that a crust can develop.

While cast-iron pans are excellent for searing multiple items, they do have some drawbacks. They can be heavy, and they may struggle with oddly shaped pieces of food. Cast-iron pans also require seasoning and maintenance to keep them in good condition. However, with proper care, a cast-iron pan can last for decades and become a trusted tool in your kitchen.

A torch can be used to sear the sides of a steak while it's cooking in a cast iron pan

A torch can be used to sear the sides of a steak while it's cooking in a cast-iron pan. This technique is known as "torch searing" and it can be used in combination with pan searing to create a delicious, evenly browned crust on your steak.

Here's a step-by-step guide to torch-searing a steak in a cast-iron pan:

Step 1: Prepare the Steak

Remove the steak from the refrigerator at least 15 minutes before cooking to bring it to room temperature. Blot the steak dry with paper towels to remove any excess moisture. This step is crucial for achieving a good sear.

Step 2: Prepare the Cast-Iron Pan

Place the cast-iron pan on the stovetop and heat it over medium-high heat for about 5-6 minutes. You can test the temperature by splashing a few drops of water onto the pan. If the water sizzles and evaporates immediately, your pan is hot enough.

Step 3: Oil the Pan and Season the Steak

Add a few tablespoons of oil to the pan, such as canola oil, avocado oil, or vegetable oil. These oils have high smoke points, which are ideal for searing steaks. Season the steak generously with salt and pepper on both sides. Don't be shy with the salt, as it will enhance the flavour of your steak.

Step 4: Sear the Steak in the Pan

Carefully place the steak in the hot pan and sear for about 2 minutes on each side. You may need to adjust the time depending on your desired level of doneness. For a medium-rare steak, aim for an internal temperature of 130-135°F (54-57°C).

Step 5: Use the Torch to Sear the Sides

While the steak is cooking in the pan, use a culinary torch to sear the sides and edges of the steak. This will ensure that all surfaces of the steak are evenly browned and develop a delicious crust. Be careful not to hold the torch too close to the steak, as it can burn the meat instead of searing it.

Step 6: Finish Cooking the Steak

Once the steak is seared on both sides and the sides are browned, you can finish cooking it to your desired level of doneness. For a thicker steak, you may want to transfer the pan to a preheated oven to ensure even cooking. Alternatively, you can continue searing in the pan, flipping the steak occasionally, until it reaches your desired temperature.

Step 7: Rest the Steak

After cooking, let the steak rest for at least 5 minutes before slicing into it. This allows the juices to redistribute, ensuring a juicy and tender steak.

Using a torch to sear the sides of a steak while it's cooking in a cast-iron pan is a great technique for creating a delicious, evenly browned crust. It can be used in combination with pan searing, as demonstrated in this guide, or as a standalone method for searing steaks. Remember to exercise caution when working with a torch, and always ensure your work area is clear of any flammable materials.
