How to Make It
In a small saucepan, combine the coconut milk, coconut sugar, salt and turmeric. Bring to a boil, stirring to dissolve the sugar. Cook until slightly thickened, about 10 minutes.
Light a grill or heat a grill pan over moderate heat. Brush the corn with some of the coconut glaze and grill, turning and basting occasionally, until slightly charred and crisp-tender, about 20 minutes. Brush the corn with more glaze and serve warm.
