Cast iron round grill pans, sizzling plate with a wooden bases 

Sizzling plates, also known as sizzlers or cast iron steak plates, are used for cooking and serving food that is still hot and "sizzling". The plate itself is made of cast iron, which is known for its excellent heat retention and even heat distribution. They are typically served on a heat-resistant wooden base, which allows the hot plate to be brought directly to the table. These plates are often used in restaurants and at home to serve a variety of dishes, including steaks, fajitas, seafood, vegetables, and even desserts like brownies. The raised ridges on the grill pan create desirable sear marks on the food. 

The plate can be heated on a stovetop or in an oven before the food is placed on it. The cast iron material allows the food to continue cooking slightly and stay hot while being served.
