I've been trying to look into methods of grilling on typical picnic grills like this one As we all know, these grills tend to be pretty nasty/not really taken care of well. So I was looking for a cleaner way of grilling. Here's what I've come up with: 1) Use tin foil, but poke holes so that the fat/runoff has somewhere to go: I've tried this before, but it doesn't really work well. The tin foil burns/gets torn easily and it's still a mess 2) Use a camp grill like this Not really sure if this will work though, since the grate will be on top of the grill and will be really far from the charcoal. 3) Use grill liners, like the ones made by Clean BBQ. Seems like a good idea, but on a lot of the reviews, it says they melt. Not sure if this works 4) Use frog mats. Another good idea, but they also have melting issues and it is explicitly stated that they are not designed for direct heat. 5) Use grill toppers like these: Of all the alternatives, this seems like the best solution, though I'm not sure about potential pitfalls, such as uneven heating, or the topper gets too messy after only grilling a small amount of meat, etc Has anyone tried any of these methods, or do you have any other suggestions? Thanks in advance.
