Char grilled corn on the cob

Microwave corn cobs for 4 mins each. This gives them an initial steam cook and loosens the husk for easy removal
Cut 2.5 cm off the bottom of the corn. Grasp the top of the husk and shake gently. The corn will drop out completely husked
Place on hot bbq to char the corn kernels, rotating only after each side has picked up a bit of char.
Brush with melted butter and serve immediately.
