To keep food from sticking, brush it with olive oil or vegetable oil before placing it on the grill. For extra protection, brush the grill with oil or spray with nonstick cooking spray before heating.
More important tips:
Grill with the top closed to retain heat and decrease cooking time.
Use tongs to turn meat or skewers as a fork punctures the food and allows juices to escape.
Before serving, always let meat rest so juices can be absorbed; burgers should rest about 2 - 4 minutes.
When serving corn on the cob, be sure to set out Butter Babies so your guests can keep their hands and clothes clean.
