— An ice cube added to the packet will provide moisture.

— Sauces, such as salsa, BBQ sauce or soy sauce, will also add moisture.

— Always use tongs or oven gloves when touching the packets during and after cooking.

"I've watched a fair number of students make foil packs, and they always forget two things," Smith said. "Seasoning (salt, pepper or spices) and adding oil or butter. Make sure that you season before cooking the pack and that you add enough fat to the bottom and the top of the foil pack so that things don't stick. And this will result in a delicious tasting meal."
