Hi all. I'm going to purchase a cast iron grill pan. There is large selection of grills with square bottom on market. And they are really more suitable for steaks cooking. I have a common electroceramic stove with round burners. I heard that it is not safe to use stove with pans that have different size (shape) than the stove burners. And I can explain that in situation when the burners are wider. Would it be right to buy square grill with the side length equal to stove burner diameter (or more)? Would it seriously affect the temperature distribution or something else? And one more question (in order not to create another topic). Is there any difference between cast iron and enamelled cast iron grill in context of steak cooking? Thanks.
