Black Cherry Grilling Planks: Whether you prefer the traditional rectangle planks or our natural oval planks, the slight almond flavor of black cherry sap adds a distinct taste to your steak grilled on a plank. If you are using your oven broiler, simply soak the plank for two hours and place on a cookie sheet. Season your steak as normal and place on the plank directly beneath the broiler element. Grill on one side and flip. Serve on the plank with a garnish of your choice for a real "wow" factor!
