The flat hot plate on a BBQ can be a suitable alternative to a cast iron skillet when cooking a steak, but there are some differences to consider.
Heat distribution: Cast iron skillets are known for their excellent heat retention and even distribution. They tend to provide more consistent heat across the surface, ensuring uniform cooking. While a flat hot plate on a BBQ can also distribute heat reasonably well, it may not be as efficient as a cast iron skillet.
Control: Cast iron skillets offer more precise control over the cooking temperature. You can adjust the heat easily and maintain it throughout the cooking process. With a flat hot plate on a BBQ, the heat may be more difficult to regulate, especially if you're cooking over an open flame. It may require some trial and error to find the right temperature.
Flavor: Many people appreciate the flavor that a well-seasoned cast iron skillet imparts to the steak. The seasoning on the skillet can enhance the taste and create a delicious crust on the meat. On the other hand, a flat hot plate on a BBQ may not provide the same depth of flavor unless it has been seasoned over time.
Ultimately, both options can produce tasty steaks, but the cast iron skillet often offers better heat control and flavor. However, if you are experienced with using the hot plate on your BBQ and can maintain consistent heat, you can still achieve excellent results. It may come down to personal preference and the equipment you have available.
