Melt the 1/4 cup butter and add the minced garlic & 2 Tablespoons of Worcestershire sauce. Set aside. If you want a milder garlic flavor, the melt the butter in a saucepan (over medium heat, or straight on the grill). Add garlic and cook until soft and fragrant, 30 seconds to 1 minute. Do not burn garlic. Remove mixture from heat. Then add the 2 Tablespoons of Worcestershire sauce and stir mixture to combine.
Brush corn with butter mixture.
Over high heat, grill corn for about 10 minutes, rotating occasionally until each side of the corn is cooked and slightly charred.
Before serving, season corn with salt and pepper then top with grated parmesan and minced parsley.
