Memorial Day is the more or less unofficial beginning of outdoor grilling, so here are some hints at making it more satisfying. Or, use canned vegetable spray just before grilling to keep foods from sticking. Use the wire brush following every use. It keeps insects and rodents from looking for a snack. Grilling times can vary depending on how often the grill lid is opened, variations in thickness of foods, and outside temperature and wind.
Most foods cook more quickly when the grill lid is closed.
It also provides a smokier flavor. Generally, don't use a fork because it will pierce the meat, allowing flavorful juices to escape. Be sure burgers are cooked until all the pink inside is gone. Always place cooked foods on a clean plate or platter, not one that has previously held uncooked meat, poultry or fish. Wash plates and cooking utensils in hot soapy water and rinse well.
