Today at Target in Jackson, MS, I purchased two Chefmate Dual Sided Reusable BBQ Sheets.Here are two pictures of what it looks like: Since they did not come with instructions, I would like to know if anyone can answer the following questions: 1. The one with the ridges is the side for searing and the other one with the holes is for grilling, correct? 2. Can you sear a steak or a hamburger or any other piece of meat on the searing side and finish grilling it on the other side? 3. Can the grilling side be used for meats as well as delicate items, like fish, shrimp, or vegetables? 4. Do you have to build direct heat/indirect heat charcoal zones when you use this product. If anyone can help me answer these questions, thank you very much.
