• Prepare the grill for direct cooking over medium-high heat (200º to 260ºC).
• Mix the patty ingredients, and then gently form four patties of equal size, each about 18 millimeters thick. With your thumb or the back of a spoon, make a shallow indentation about 2.5 centimeters) wide in the center of the patties to keep them from forming a dome as they cook. Refrigerate until ready to grill.
• Brush the cooking grates clean. Grill the patties over direct medium-high heat, with the lid closed, until cooked to medium doneness, 8 to 10 minutes, brushing with the remaining glaze every 2 minutes and turning them once when the patties release easily from the grate without sticking. During the last minute of cooking time, place a slice of cheese on each patty to melt. Remove from the grill.
