Ensure your scallops are very dry before marinating to achieve a good sear on the grill. Soaking the wooden skewers prevents them from burning on the grill. Don't overcrowd the skewers; allow enough space between the mushrooms and scallops for even cooking. For enhanced flavor, consider adding a pinch of red pepper flakes to the scallop marinade. Serve immediately to enjoy the scallops and mushrooms at their peak of tenderness and flavor.
