If you want to cook the corn in their husks, no problem. Arrange the corn on a large tray and roast for between 35-40 minutes. To test if it's ready, pull back just enough husk to check that the corn is tender with shiny, slightly browned kernels. After removing the roasted corn from the oven, allow it to cool for around 15 minutes. Then, use a kitchen towel to grab the base of the corn and carefully peel back the husks and silks. Top with your toppings of choice and enjoy.
