Combine ingredients. Form into 4 burgers. Grill until well-done.
Grilling over high heat can create compounds called heterocyclic amines, which are potential carcinogens. Because these HCAs form within cooked meat, poultry and fish, you can’t get rid of them by scraping off char. However, there are several cooking methods that have been proven to dramatically reduce the formation of HCAs.
Try a “fruit burger.” Mixing a pound of ground meat with a cup of ground, fresh, tart cherries or blueberries before grilling suppresses 90% of HCA formation, according to research at Michigan State. A possible reason: Cherries are high in HCA-blocking antioxidants. Researchers say other deep-colored fruits rich in antioxidants (grapes, currants or plums) should work, too.
