To choose a charcoal grill, consider how big you want it. Some portable grills are small, and can only accommodate two or three chicken breasts. A grill with over 300 square inches of cooking space should be more than enough for a family of four. You also want to make sure the grill is easy to clean. Digging out the ashes of a poorly designed grill can be a real pain. Temperature control is a plus, but for fine-tuning heat, you may need to spend more for a grill with more features. And watch your wallet. It’s always a good idea to start with a budget. Luckily, there are a lot of great grills that cost less than $150.
